EuroPython 2020: Opening our Merchandise Shop
by M.-A. Lemburg June 23, 2020

June 23, 2020

We’re very happy to announce our very own EuroPython merchandise shop: * EuroPython Merch Shop * https://shop.spreadshirt.ie/europython/ Customize your conference t-shirt for EP2020 -------------------------------------------- The shop is run on the Spreadshirt platform and so Spreadshirt will handle all payments, invoicing and shipping. Since we’re running EuroPython 2020 as an online event, we will not be giving out conference bags or t-shirts this year, as we do for the in-person event. Instead, we give you the opportunity to choose among the many products we have put up in the shop, and order the color and size completely individually. Any profit this creates will go towards the EuroPython 2021 financial aid budget, so will be put to good use. Save 15% until July 5 --------------------- Spreadshirt is giving a 15% discount on the prices until July 5, 23:59 UTC, so if you’re ordering in the next few days, you can still get your shirt in time for the conference. Shipping worldwide ------------------ Spreadshirt is shipping to a lot of destinations worldwide. Unfortunately, they don’t support shipping to the US, Australia, Brasil and a few other countries on their European shop system. Since the US taxation system is too complex for us to handle at the moment, we have not created a corresponding US shop yet. We will look into this later this year. Help spread the word -------------------- Please help us spread this message by sharing it on your social networks as widely as possible. Thank you !

[ANN] Austin -- Python frame stack sampler for CPython v1.0.1 is now available
by Gabriele June 21, 2020

June 21, 2020

I am delighted to announce the release 1.0.1 of Austin. If you haven't heard of Austin before, it is a frame stack sampler for CPython. It can be used to obtain statistical profiling data out of a running Python application without a single line of instrumentation. This means that you can start profiling a Python application straightaway, even while it's running on a production environment, with minimal impact on performance. The simplest way of using Austin is by piping its output to FlameGraph for a quick and detailed representation of the collected samples. The latest release introduces a memory profiling mode which allows you to profile memory usage. Austin is a pure C application that has no other dependencies other than the C standard library. Its source code is hosted on GitHub at https://github.com/P403n1x87/austin The README contains installation and usage details, as well as some examples of Austin in action. Details on how to contribute to Austin's development can be found at the bottom of the page. Austin v1.0.1 is also the first version of Austin to be available from Homebrew for easy installation on MacOS. These are the other places where Austin can be downloaded Linux: - Snap Store - Debian repositories Windows: - Chocolatey Furthermore, you can stay up-to-date with the project's development by following Austin on Twitter (https://twitter.com/AustinSampler). All the best, Gabriele Bugfixes ======== - Fixed Python 3.8 support on MacOS.

ANN: SciPy 1.5.0
by Tyler Reddy June 21, 2020

June 21, 2020

Hi all, On behalf of the SciPy development team I'm pleased to announce the release of SciPy 1.5.0. Sources and binary wheels can be found at: https://pypi.org/project/scipy/ and at: https://github.com/scipy/scipy/releases/tag/v1.5.0 One of a few ways to install this release with pip: pip install scipy==1.5.0 ========================== SciPy 1.5.0 Release Notes ========================== SciPy 1.5.0 is the culmination of 6 months of hard work. It contains many new features, numerous bug-fixes, improved test coverage and better documentation. There have been a number of deprecations and API changes in this release, which are documented below. All users are encouraged to upgrade to this release, as there are a large number of bug-fixes and optimizations. Before upgrading, we recommend that users check that their own code does not use deprecated SciPy functionality (to do so, run your code with ``python -Wd`` and check for ``DeprecationWarning`` s). Our development attention will now shift to bug-fix releases on the 1.5.x branch, and on adding new features on the master branch. This release requires Python 3.6+ and NumPy 1.14.5 or greater. For running on PyPy, PyPy3 6.0+ and NumPy 1.15.0 are required. Highlights of this release ---------------------------------- - wrappers for more than a dozen new ``LAPACK`` routines are now available in `scipy.linalg.lapack` - Improved support for leveraging 64-bit integer size from linear algebra backends - addition of the probability distribution for two-sided one-sample Kolmogorov-Smirnov tests New features ============ `scipy.cluster` improvements --------------------------------------- Initialization of `scipy.cluster.vq.kmeans2` using ``minit="++"`` had a quadratic complexity in the number of samples. It has been improved, resulting in a much faster initialization with quasi-linear complexity. `scipy.cluster.hierarchy.dendrogram` now respects the ``matplotlib`` color palette `scipy.fft` improvements ---------------------------------- A new keyword-only argument ``plan`` is added to all FFT functions in this module. It is reserved for passing in a precomputed plan from libraries providing a FFT backend (such as ``PyFFTW`` and ``mkl-fft``), and it is currently not used in SciPy. `scipy.io` improvements --------------------------------- `scipy.io.wavfile` error messages are more explicit about what's wrong, and extraneous bytes at the ends of files are ignored instead of raising an error when the data has successfully been read. `scipy.io.loadmat` gained a ``simplify_cells`` parameter, which if set to ``True`` simplifies the structure of the return value if the ``.mat`` file contains cell arrays. ``pathlib.Path`` objects are now supported in `scipy.io` Matrix Market I/O functions `scipy.linalg` improvements -------------------------------------- `scipy.linalg.eigh` has been improved. Now various ``LAPACK`` drivers can be selected at will and also subsets of eigenvalues can be requested via ``subset_by_value`` keyword. Another keyword ``subset_by_index`` is introduced. Keywords ``turbo`` and ``eigvals`` are deprecated. Similarly, standard and generalized Hermitian eigenvalue ``LAPACK`` routines ``?<sy/he>evx`` are added and existing ones now have full ``_lwork`` counterparts. Wrappers for the following ``LAPACK`` routines have been added to `scipy.linalg.lapack`: - ``?getc2``: computes the LU factorization of a general matrix with complete pivoting - ``?gesc2``: solves a linear system given an LU factorization from ``?getc2`` - ``?gejsv``: computes the singular value decomposition of a general matrix with higher accuracy calculation of tiny singular values and their corresponding singular vectors - ``?geqrfp``: computes the QR factorization of a general matrix with non-negative elements on the diagonal of R - ``?gtsvx``: solves a linear system with general tridiagonal matrix - ``?gttrf``: computes the LU factorization of a tridiagonal matrix - ``?gttrs``: solves a linear system given an LU factorization from ``?gttrf`` - ``?ptsvx``: solves a linear system with symmetric positive definite tridiagonal matrix - ``?pttrf``: computes the LU factorization of a symmetric positive definite tridiagonal matrix - ``?pttrs``: solves a linear system given an LU factorization from ``?pttrf`` - ``?pteqr``: computes the eigenvectors and eigenvalues of a positive definite tridiagonal matrix - ``?tbtrs``: solves a linear system with a triangular banded matrix - ``?csd``: computes the Cosine Sine decomposition of an orthogonal/unitary matrix Generalized QR factorization routines (``?geqrf``) now have full ``_lwork`` counterparts. `scipy.linalg.cossin` Cosine Sine decomposition of unitary matrices has been added. The function `scipy.linalg.khatri_rao`, which computes the Khatri-Rao product, was added. The new function `scipy.linalg.convolution_matrix` constructs the Toeplitz matrix representing one-dimensional convolution. `scipy.optimize` improvements ----------------------------------------- The finite difference numerical differentiation used in various ``minimize`` methods that use gradients has several new features: - 2-point, 3-point, or complex step finite differences can be used. Previously only a 2-step finite difference was available. - There is now the possibility to use a relative step size, previously only an absolute step size was available. - If the ``minimize`` method uses bounds the numerical differentiation strictly obeys those limits. - The numerical differentiation machinery now makes use of a simple cache, which in some cases can reduce the number of function evaluations. - ``minimize``'s ``method= 'powell'`` now supports simple bound constraints There have been several improvements to `scipy.optimize.linprog`: - The ``linprog`` benchmark suite has been expanded considerably. - ``linprog``'s dense pivot-based redundancy removal routine and sparse presolve are faster - When ``scikit-sparse`` is available, solving sparse problems with ``method='interior-point'`` is faster The caching of values when optimizing a function returning both value and gradient together has been improved, avoiding repeated function evaluations when using a ``HessianApproximation`` such as ``BFGS``. ``differential_evolution`` can now use the modern ``np.random.Generator`` as well as the legacy ``np.random.RandomState`` as a seed. `scipy.signal` improvements -------------------------------------- A new optional argument ``include_nyquist`` is added to ``freqz`` functions in this module. It is used for including the last frequency (Nyquist frequency). `scipy.signal.find_peaks_cwt` now accepts a ``window_size`` parameter for the size of the window used to calculate the noise floor. `scipy.sparse` improvements ---------------------------------------- Outer indexing is now faster when using a 2d column vector to select column indices. `scipy.sparse.lil.tocsr` is faster Fixed/improved comparisons between pydata sparse arrays and sparse matrices BSR format sparse multiplication performance has been improved. `scipy.sparse.linalg.LinearOperator` has gained the new ``ndim`` class attribute `scipy.spatial` improvements --------------------------------------- `scipy.spatial.geometric_slerp` has been added to enable geometric spherical linear interpolation on an n-sphere `scipy.spatial.SphericalVoronoi` now supports calculation of region areas in 2D and 3D cases The tree building algorithm used by ``cKDTree`` has improved from quadratic worst case time complexity to loglinear. Benchmarks are also now available for building and querying of balanced/unbalanced kd-trees. `scipy.special` improvements ---------------------------------------- The following functions now have Cython interfaces in `cython_special`: - `scipy.special.erfinv` - `scipy.special.erfcinv` - `scipy.special.spherical_jn` - `scipy.special.spherical_yn` - `scipy.special.spherical_in` - `scipy.special.spherical_kn` `scipy.special.log_softmax` has been added to calculate the logarithm of softmax function. It provides better accuracy than ``log(scipy.special.softmax(x))`` for inputs that make softmax saturate. `scipy.stats` improvements ------------------------------------ The function for generating random samples in `scipy.stats.dlaplace` has been improved. The new function is approximately twice as fast with a memory footprint reduction between 25 % and 60 % (see gh-11069). `scipy.stats` functions that accept a seed for reproducible calculations using random number generation (e.g. random variates from distributions) can now use the modern ``np.random.Generator`` as well as the legacy ``np.random.RandomState`` as a seed. The ``axis`` parameter was added to `scipy.stats.rankdata`. This allows slices of an array along the given axis to be ranked independently. The ``axis`` parameter was added to `scipy.stats.f_oneway`, allowing it to compute multiple one-way ANOVA tests for data stored in n-dimensional arrays. The performance of ``f_oneway`` was also improved for some cases. The PDF and CDF methods for ``stats.geninvgauss`` are now significantly faster as the numerical integration to calculate the CDF uses a Cython based ``LowLevelCallable``. Moments of the normal distribution (`scipy.stats.norm`) are now calculated using analytical formulas instead of numerical integration for greater speed and accuracy Moments and entropy trapezoidal distribution (`scipy.stats.trapz`) are now calculated using analytical formulas instead of numerical integration for greater speed and accuracy Methods of the truncated normal distribution (`scipy.stats.truncnorm`), especially ``_rvs``, are significantly faster after a complete rewrite. The `fit` method of the Laplace distribution, `scipy.stats.laplace`, now uses the analytical formulas for the maximum likelihood estimates of the parameters. Generation of random variates is now thread safe for all SciPy distributions. 3rd-party distributions may need to modify the signature of the ``_rvs()`` method to conform to ``_rvs(self, ..., size=None, random_state=None)``. (A one-time VisibleDeprecationWarning is emitted when using non-conformant distributions.) The Kolmogorov-Smirnov two-sided test statistic distribution (`scipy.stats.kstwo`) was added. Calculates the distribution of the K-S two-sided statistic ``D_n`` for a sample of size n, using a mixture of exact and asymptotic algorithms. The new function ``median_abs_deviation`` replaces the deprecated ``median_absolute_deviation``. The ``wilcoxon`` function now computes the p-value for Wilcoxon's signed rank test using the exact distribution for inputs up to length 25. The function has a new ``mode`` parameter to specify how the p-value is to be computed. The default is ``"auto"``, which uses the exact distribution for inputs up to length 25 and the normal approximation for larger inputs. Added a new Cython-based implementation to evaluate guassian kernel estimates, which should improve the performance of ``gaussian_kde`` The ``winsorize`` function now has a ``nan_policy`` argument for refined handling of ``nan`` input values. The ``binned_statistic_dd`` function with ``statistic="std"`` performance was improved by ~4x. ``scipy.stats.kstest(rvs, cdf,...)`` now handles both one-sample and two-sample testing. The one-sample variation uses `scipy.stats.ksone` (or `scipy.stats.kstwo` with back off to `scipy.stats.kstwobign`) to calculate the p-value. The two-sample variation, invoked if ``cdf`` is array_like, uses an algorithm described by Hodges to compute the probability directly, only backing off to `scipy.stats.kstwo` in case of overflow. The result in both cases is more accurate p-values, especially for two-sample testing with smaller (or quite different) sizes. `scipy.stats.maxwell` performance improvements include a 20 % speed up for `fit()`` and 5 % for ``pdf()`` `scipy.stats.shapiro` and `scipy.stats.jarque_bera` now return a named tuple for greater consistency with other ``stats`` functions Deprecated features ================ `scipy` deprecations ---------------------------- `scipy.special` changes -------------------------------- The ``bdtr``, ``bdtrc``, and ``bdtri`` functions are deprecating non-negative non-integral ``n`` arguments. `scipy.stats` changes ----------------------------- The function ``median_absolute_deviation`` is deprecated. Use ``median_abs_deviation`` instead. The use of the string ``"raw"`` with the ``scale`` parameter of ``iqr`` is deprecated. Use ``scale=1`` instead. Backwards incompatible changes ========================== `scipy.interpolate` changes ------------------------------------- `scipy.linalg` changes ------------------------------ The output signatures of ``?syevr``, ``?heevr`` have been changed from ``w, v, info`` to ``w, v, m, isuppz, info`` The order of output arguments ``w``, ``v`` of ``<sy/he>{gv, gvd, gvx}`` is swapped. `scipy.signal` changes ------------------------------- The output length of `scipy.signal.upfirdn` has been corrected, resulting outputs may now be shorter for some combinations of up/down ratios and input signal and filter lengths. `scipy.signal.resample` now supports a ``domain`` keyword argument for specification of time or frequency domain input. Other changes ============= Improved support for leveraging 64-bit integer size from linear algebra backends in several parts of the SciPy codebase. Shims designed to ensure the compatibility of SciPy with Python 2.7 have now been removed. Many warnings due to unused imports and unused assignments have been addressed. Many usage examples were added to function docstrings, and many input validations and intuitive exception messages have been added throughout the codebase.

NumPy 1.19.0 released
by Charles R Harris June 20, 2020

June 20, 2020

Hi All, On behalf of the NumPy team I am pleased to announce that NumPy 1.19.0 has been released. This NumPy release supports Python 3.6-3.8 and is marked by the removal of much technical debt: support for Python 2 has been removed, many deprecations have been expired, and documentation has been improved. The polishing of the random module continues apace with bug fixes and better usability from Cython. Perhaps the most interesting thing for users will be the availability of wheels for aarch64 and PyPY. Downstream developers should use Cython >= 0.29.16 for Python 3.8 support and OpenBLAS >= 3.7 to avoid wrong results on the Skylake architecture. The NumPy Wheels for this release can be downloaded from PyPI <https://pypi.org/project/numpy/1.19.0/>, source archives, release notes, and wheel hashes are available from Github <https://github.com/numpy/numpy/releases/tag/v1.19.0>. Linux users will need pip >= 0.19.3 in order to install manylinux2010 and manylinux2014 wheels. *Contributors* A total of 126 people contributed to this release. People with a "+" by their names contributed a patch for the first time. - Alex Henrie - Alexandre de Siqueira + - Andras Deak - Andrea Sangalli + - Andreas Klöckner + - Andrei Shirobokov + - Anirudh Subramanian + - Anne Bonner - Anton Ritter-Gogerly + - Benjamin Trendelkamp-Schroer + - Bharat Raghunathan - Brandt Bucher + - Brian Wignall - Bui Duc Minh + - Changqing Li + - Charles Harris - Chris Barker - Chris Holland + - Christian Kastner + - Chunlin + - Chunlin Fang + - Damien Caliste + - Dan Allan - Daniel Hrisca - Daniel Povey + - Dustan Levenstein + - Emmanuelle Gouillart + - Eric Larson - Eric M.

ftputil 4.0.0 released
by Stefan Schwarzer June 13, 2020

June 13, 2020

ftputil 4.0.0 is now available from https://ftputil.sschwarzer.net/download and https://pypi.org/project/ftputil/ Changes since the last stable release 3.4 ----------------------------------------- Backward-incompatible changes ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This ftputil version isn't fully backward-compatible with the previous version. The backward-incompatible changes are: - Python 2 is no longer supported. - The minimum supported Python 3 version is 3.6. - By default, time stamps in directory listings coming from the server are now assumed to be in UTC. Previously, listings were assumed to use the local time of the client. [1] Correspondingly, the definition of "time shift" has changed. The time shift is now defined as the time zone used in server listings (say, UTC+02:00) and UTC, in other words, the time shift now is the time zone offset applied in the server listings. In earlier ftputil versions, the time shift was defined as "time used in server listings" minus "local client time." - The flag `use_list_a_option` of `FTPHost` instances is now set to `False` by default. This option was intended to make life easier for users, but turned out to be problematic [2]. - As in `os.makedirs`, `FTPHost.makedirs` now supports the `exist_ok` flag and uses the default of `False`. You can get the behavior of ftputil 3.x by passing `exist_ok=True`. [3] If you need to use Python versions before 3.6, please use the previous stable ftputil version 3.4. Other changes ~~~~~~~~~~~~~ - Functions and methods which used to accept only `str` or `bytes` paths now _also_ accept `PathLike` objects [4, 5]. - Clear the stat cache when setting a new time shift value. [6] - ftputil now officially follows semantic versioning (SemVer) [7]. Actually ftputil has been following semantic versioning since a long time (probably since version 2.0 in 2004), but it was never explicitly guaranteed and new major versions were named x.0 instead of x.0.0 and new minor versions x.y instead of x.y.0. - Internal changes: The tests were moved to pytest. The old mocking approach was replaced by a "scripted session" approach. What is ftputil? ---------------- ftputil is a high-level FTP client library for the Python programming language. ftputil implements a virtual file system for accessing FTP servers, that is, it can generate file-like objects for remote files. The library supports many functions similar to those in the `os`, `os.path` and `shutil` modules. ftputil has convenience functions for conditional uploads and downloads, and handles FTP clients and servers in different timezones. See the documentation for details: https://ftputil.sschwarzer.net/trac/wiki/Documentation https://ftputil.sschwarzer.net/trac/wiki/WhatsNewInFtputil4.0.0 License ------- ftputil is open source software, released under the 3-clause BSD license (see https://opensource.org/licenses/BSD-3-Clause ). [1] https://ftputil.sschwarzer.net/trac/ticket/134 [2] https://ftputil.sschwarzer.net/trac/ticket/110 [3] https://ftputil.sschwarzer.net/trac/ticket/117 [4] https://docs.python.org/3/library/os.html#os.PathLike [5] https://ftputil.sschwarzer.net/trac/ticket/119 [6] https://ftputil.sschwarzer.net/trac/ticket/136 [7] https://semver.org/ Best regards, Stefan

PyDev 7.6.0 Released
by Fabio Zadrozny June 11, 2020

June 11, 2020

PyDev 7.6.0 Release Highlights - *Debugger improvements* (updated to pydevd 1.9.1). - *Variables are now grouped* (special/class/function/protected) -- note: it's possible to hide groups in the variables view menu dropdown. - When a launching a subprocess does not target a python executable, the original args are kept (so, quotes are no longer trimmed). - A step in which would skip code won't be reported in the return if it'd reach the same location. - The disassembled version of a frame may be shown if the sources are not available. - PySide2 is supported to recognize QThreads/event loop in interactive console. - *Python 3.8 parsing fixes* - Properly parsing f-strings with named unicode character. i.e.: *f"\N{BULLET}"*. - Properly parsing f-strings formats using colon. i.e.: *f"{datetime.datetime.now():%Y-%m-%d %H:%M:%S}"*. - Properly parsing f-strings with vars ending in equals. i.e.: *f'{y=}'*. - Properly parsing raw f-strings such as *rf"str"*. - Properly parsing iterable unpacking syntax. i.e.: *return lastname.upper(), *members*. - Support for the latest version of PyTest (which may resolve symlinks and changed the TerminalWriter import location). - PyDev package explorer is a bit faster (cache source project paths for a project). - Recognizing type comments for *self* attributes. i.e.: *#: :type self.var: MyClass*. - Trailing commas properly recognized in automatic import. About PyDev PyDev is an open-source Python IDE on top of Eclipse for Python, Jython and IronPython development, now also available for Python on Visual Studio Code. It comes with goodies such as code completion, syntax highlighting, syntax analysis, code analysis, refactor, debug, interactive console, etc. It is also available as a standalone through LiClipse with goodies such as multiple cursors, theming and support for many other languages, such as Django Templates, Jinja2, Html, JavaScript, etc. Links: PyDev: http://pydev.org PyDev Blog: http://pydev.blogspot.com PyDev on VSCode: http://pydev.org/vscode LiClipse: http://www.liclipse.com PyVmMonitor - Python Profiler: http://www.pyvmmonitor.com/ Cheers, Fabio Zadrozny

[RELEASE] Python 3.9.0b3 is now available for testing
by Łukasz Langa June 9, 2020

June 9, 2020

On behalf of the entire Python development community, and the currently serving Python release team in particular, I’m pleased to announce the release of Python 3.9.0b3. Get it here: https://www.python.org/downloads/release/python-390b3/ <https://www.python.org/downloads/release/python-390b3/> Wait, Beta 3? What happened to Beta 2? Beta 2? Speak of him no more. We disappeared him. He was a bad release. Truly awful. I get shivers just thinking about it. Never mention that name again in this house. I mean, long story short, in Beta 2 you couldn’t do urllib.request.urlopen("https://www.python.org").read() because it wouldn’t find root certificates due to a bug <https://bugs.python.org/issue40924>. Since this was a problem only apparent on an installed Python, it wasn’t identified by unit tests and was only found by Ned while he was testing his Mac installer. By the time we learned of the severity of the bug I already tagged and published the release on python.org <http://python.org/>. That’s why we couldn’t just re-do the release under the same version. Sorry for the trouble. We’re tweaking our release process to catch this problem sooner in future releases. Now, back to regular programming… This is a beta preview of Python 3.9 Python 3.9 is still in development. This release, 3.9.0b3, is the third of five planned beta release previews. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. Call to action We strongly encourage maintainers of third-party Python projects to test with 3.9 during the beta phase and report issues found to the Python bug tracker <https://bugs.python.org/> as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2020-08-10). Our goal is have no ABI changes after beta 5 and as few code changes as possible after 3.9.0rc1, the first release candidate. To achieve that, it will be extremely important to get as much exposure for 3.9 as possible during the beta phase. Please keep in mind that this is a preview release and its use is not recommended for production environments. Major new features of the 3.9 series, compared to 3.8 Some of the new major new features and changes in Python 3.9 are: PEP 584 <https://www.python.org/dev/peps/pep-0584/>, Union Operators in dict PEP 585 <https://www.python.org/dev/peps/pep-0585/>, Type Hinting Generics In Standard Collections PEP 593 <https://www.python.org/dev/peps/pep-0593/>, Flexible function and variable annotations PEP 602 <https://www.python.org/dev/peps/pep-0602/>, Python adopts a stable annual release cadence PEP 616 <https://www.python.org/dev/peps/pep-0616/>, String methods to remove prefixes and suffixes PEP 617 <https://www.python.org/dev/peps/pep-0617/>, New PEG parser for CPython BPO 38379 <https://bugs.python.org/issue38379>, garbage collection does not block on resurrected objects; BPO 38692 <https://bugs.python.org/issue38692>, os.pidfd_open added that allows process management without races and signals; BPO 39926 <https://bugs.python.org/issue39926>, Unicode support updated to version 13.0.0; BPO 1635741 <https://bugs.python.org/issue1635741>, when Python is initialized multiple times in the same process, it does not leak memory anymore; A number of Python builtins (range, tuple, set, frozenset, list, dict) are now sped up using PEP 590 <https://www.python.org/dev/peps/pep-0590> vectorcall; A number of Python modules (_abc, audioop, _bz2, _codecs, _contextvars, _crypt, _functools, _json, _locale, operator, resource, time, _weakref) now use multiphase initialization as defined by PEP 489 <https://www.python.org/dev/peps/pep-0489/>; A number of standard library modules (audioop, ast, grp, _hashlib, pwd, _posixsubprocess, random, select, struct, termios, zlib) are now using the stable ABI defined by PEP 384 <https://www.python.org/dev/peps/pep-0384/>. (Hey, fellow core developer, if a feature you find important is missing from this list, let Łukasz know <mailto:lukasz@python.org>.) The next pre-release, the fourth beta release of Python 3.9, will be 3.9.0b4. It is currently scheduled for 2020-06-29.

fades 9.0
by Facundo Batista June 8, 2020

June 8, 2020

Hello all, We're glad to announce the release of fades 9.0. fades is a system that automatically handles the virtualenvs in the cases normally found when writing scripts and simple programs, and even helps to administer big projects. It will automagically create a new virtualenv (or reuse a previous created one), installing the necessary dependencies, and execute your script inside that virtualenv. You only need to execute the script with fades (instead of Python) and also mark the required dependencies. More details here: http://fades.rtfd.org/ What's new in this release? - Get pip automatically upgraded to latest version on each virtualenv creation (unless explicitly avoided) - Provides the --freeze parameter, which dumps the detailed package information of the virtualenv, to duplicate future installations. - The -x/--exec parameter behaviour is extended/normalized to support arbitrary paths. - Has the --autoimport parameter to automatically import the dependencies to the interactive interpreter - Added more examples and descriptions to the documentation - Improved argument parsing when fades is used in the shebang - Worked on infrastructure: better testing, multiplatform installation support, etc. Nicolás and I want to say a big thank you to the following collaborators that helped to improve and enhance fades in different ways for this version (in alphabetical order): Alejandro Dau -https://github.com/alejandrodau Carlos Joel -https://github.com/c0x6a Diego Mascialino - https://github.com/dmascialino Eduardo Enriquez - https://github.com/eduzen Iñaki Malerba - https://github.com/inakimalerba To install and enjoy fades... - If you are in Ubuntu or Debian, you can easily install like this (but probably won't get *latest* fades: sudo apt-get install fades - For not latest debian/ubuntu you have a .deb here (with its Debian source file): http://ftp.debian.org/debian/pool/main/f/fades/fades_9.0.1-1_all.deb http://ftp.debian.org/debian/pool/main/f/fades/fades_9.0.1-1.dsc - Install it in Arch is very simple: yaourt -S fades - In any Linux if you have the Snap system: snap install fades - Using pip if you want: pip3 install fades - You can always get the multiplatform tarball and install it in the old fashion way: wget http://ftp.debian.org/debian/pool/main/f/fades/fades_9.0.1.orig.tar.gz tar -xf fades_*.tar.gz cd fades-* sudo ./setup.py install Help / questions: - You can ask any question or send any recommendation or request in the Telegram group: https://t.me/fadesmagic - Also, you can open an issue here (please do if you find any problem!). https://github.com/PyAr/fades/issues/new - The project itself is in https://github.com/PyAr/fades It's very easy to run latest development version: git clone https://github.com/PyAr/fades.git cd fades bin/fades Thanks in advance for your time! -- .
