PyCon ZA 2020 - Call for Submissions
by Neil Muller 12 Nov '20

12 Nov '20

PyCon ZA 2020 will take place on the 8th & 9th of October, 2020. This year, due to the ongoing uncertainty of when conference facilities will be allowed to open, we will be running PyCon ZA as an online event. We are looking for the following presentations: - Keynotes (45 minute long talks on a subject of general interest) - Talks (30 minute long talks on more specific topics) If you would like to give a presentation, please register at https://za.pycon.org/ and submit your proposal, following the instructions at https://za.pycon.org/talks/submit-talk/ . We have a number of tracks available, including: Data Science, Teaching and Learning with Python, Web, Scientific Computing, Testing and Other (which includes all talks that don't fall under the mentioned tracks). We hope to notify accepted presenters by no later than the 31st of August 2020. Speakers will be expected to be available after the presentation for a short Q&A session. Shared sessions are also possible. The presentations will be in English. PyCon ZA offers a mentorship program for inexperienced speakers. If you would like assistance preparing your submission, email team(a)za.pycon.org with a rough draft of your talk proposal and we'll find a suitable experienced speaker to act as a mentor. If you want to present something else at PyCon ZA, please contact the organising committee at team(a)za.pycon.org . We’re researching which software platforms will be most suitable for running PyCon ZA. As soon as we have finalised this decision, we’ll make it public and update potential presenters. If you have experience with presenting on particular platforms, we'd love to hear from you at team(a)za.pycon.org . -- Neil Muller On behalf of the PyCon ZA organising committee

pip 20.2 release, plus changes coming in 20.3
by Sumana Harihareswara 01 Oct '20

01 Oct '20

On behalf of the Python Packaging Authority, I am pleased to announce that we have just released pip 20.2, a new version of pip. You can install it by running python -m pip install --upgrade pip. The highlights for this release are: - The beta of the next-generation dependency resolver is available - Faster installations from wheel files - Improved handling of wheels containing non-ASCII file contents - Faster `pip list` using parallelized network operations - Installed packages now contain metadata about whether they were directly requested by the user (PEP 376’s REQUESTED file) The new dependency resolver is *off by default* because it is *not yet ready for everyday use*. The new dependency resolver is significantly stricter and more consistent when it receives incompatible instructions, and reduces support for certain kinds of constraints files, so some workarounds and workflows may break. Please test it with the `--use-feature=2020-resolver` flag. Please see our guide on how to test and migrate, and how to report issues <https://pip.pypa.io/en/latest/user_guide/#changes-to-the-pip-dependency-res…>. We are preparing to change the default dependency resolution behavior and make the new resolver the default in pip 20.3 (in October 2020). This release also partially optimizes pip’s network usage during installation (as part of a Google Summer of Code project by McSinyx <https://summerofcode.withgoogle.com/projects/#5428041779511296>). Please test it with `pip install --use-feature=2020-resolver --use-feature=fast-deps` and report bugs to the issue tracker <https://github.com/pypa/pip/issues/new?template=bug-report.md>. This functionality is *still experimental* and *not ready for everyday use*. You can find more details (including deprecations and removals) in the changelog <https://pip.pypa.io/en/stable/news/>. As with all pip releases, a significant amount of the work was contributed by pip’s user community. Huge thanks to all who have contributed, whether through code, documentation, issue reports and/or discussion. Your help keeps pip improving, and is hugely appreciated. Specific thanks go to Mozilla (through its Mozilla Open Source Support <https://www.mozilla.org/en-US/moss/> Awards) and to the Chan Zuckerberg Initiative <https://chanzuckerberg.com/eoss/> DAF, an advised fund of Silicon Valley Community Foundation, for their funding that enabled substantial work on the new resolver. -- Sumana Harihareswara pip project manager via contract with PSF Changeset Consulting https://changeset.nyc

Corrected: leoAst.py creates two-way links between tokens and ast nodes
by Edward K. Ream 26 Jul '20

26 Jul '20

In the initial announcement, the link to leoAst.py was incorrect. The correct link is to leoAst.py in Leo's "devel" branch: https://github.com/leo-editor/leo-editor/blob/devel/leo/core/leoAst.py Alas, the link did not generate a 404, but instead linked to way obsolete code. My apologies for the confusion this has already caused. Edward ------------------------------------------------------------------------------------------ Edward K.

ANN: leoAst.py creates two-way links between tokens and ast nodes
by Edward K. Ream 25 Jul '20

25 Jul '20

*Overview* leoAst.py <https://github.com/leo-editor/leo-editor/blob/fstrings/leo/core/leoAst.py> unifies python's token-oriented and ast-oriented worlds. leoAst.py defines classes that create two-way links between *tokens* created by python's tokenize module <https://docs.python.org/3/library/tokenize.html> and *parse tree nodes* created by python's ast module <https://docs.python.org/3/library/ast.html>: The *Token Order Generator* (TOG) class *quickly* creates the following links: - An *ordered* *children* array from each ast node to its children. Order matters! - A *parent* link from each ast.node to its parent. - Two-way links between tokens in the *token list*, a list of Token objects, and the ast nodes in the parse tree: - For each token, *token.node* contains the ast.node "responsible" for the token. - For each ast node, *node.first_i* and *node.last_i* are indices into the token list. These indices give the range of tokens that can be said to be "generated" by the ast node. Once the TOG class has inserted parent/child links, the *Token Order Traverser* (TOT) class traverses trees annotated with parent/child links extremely quickly. *Contents of leoAst.py* leoAst.py is completely independent of Leo <http://leoeditor.com/>. leoAst.py contains: - The TOG and TOT classes. - An *AstDumper* class that shows these links in various formats. - Unit tests that completely cover the TOG and TOT classes. - All necessary support code - An entirely new implementation of *fstringify* <https://pypi.org/project/fstringify/>. - *Orange*, an entirely new implementation of *black* <https://pypi.org/project/black/>. *Usage* usage: leoAst.py (--help | --pytest | --unittest) OR leoAst.py (--fstringify | --fstringify-diff | --orange | --orange-diff) PATHS positional arguments: PATHS directory or list of files optional arguments: -h, --help show this help message and exit --fstringify leonine fstringify --fstringify-diff show fstringify diff --orange leonine Black --orange-diff show orange diff --pytest run pytest --unittest run unittest.main() *Applicability and importance* Many python developers will find asttokens <https://github.com/gristlabs/asttokens> meets all their needs. asttokens is well documented and easy to use. Nevertheless, two-way links are significant additions to python's tokenize <https://docs.python.org/3/library/tokenize.html> and ast <https://docs.python.org/3/library/ast.html> modules: - Links from tokens to nodes are assigned to the nearest possible ast node, not the nearest statement, as in asttokens. Links can easily be reassigned, if desired. - The TOG and TOT classes are intended to be the foundation of tools such as *fstringify* <https://pypi.org/project/fstringify/> and *black* <https://pypi.org/project/black/>. - The TOG class solves real problems, such as: how-to-get-source-corresponding-to-a-python-ast-node <https://stackoverflow.com/questions/16748029/>. *Figures of merit* *Simplicity*: The code consists primarily of a set of generators, one for every kind of ast node. *Speed*: The TOG creates two-way links between tokens and ast nodes in roughly the time taken by python's tokenize.tokenize and ast.parse library methods. This is substantially faster than the asttokens <https://pypi.org/project/asttokens/>, fstringify <https://pypi.org/project/fstringify/>, and black <https://pypi.org/project/black/> tools. The TOT class traverses trees annotated with parent/child links even more quickly. *Memory*: The TOG class makes no significant demands on python's resources. Generators add nothing to python's call stack. TOG.node_stack is the only variable-length data. This stack resides in python's heap, so its length is unimportant. In the worst case, it might contain a few thousand entries. The TOT class uses no variable-length data at all. *Links* - Theory of operation <http://leoeditor.com/appendices.html#tokenorder-classes-theory-of-operation> . - Project history <https://github.com/leo-editor/leo-editor/issues/1440#issuecomment-574145510> . - A stack overflow discussion that mentions Leo's deprecated TokenSync class <https://stackoverflow.com/questions/7456933/>, an earlier attempt at plugging the holes in python's api.

NumPy 1.19.1 released.
by Charles R Harris 22 Jul '20

22 Jul '20

Hi All, On behalf of the NumPy team I am pleased to announce that NumPy 1.19.1 has been released. This release supports Python 3.6-3.8 and may be built with the latest Python 3.9 beta. It fixes several bugs found in the 1.19.0 release, replaces several functions deprecated in the upcoming Python-3.9 release, has improved support for AIX, and has a number of development related updates to keep CI working with recent upstream changes. Downstream developers should use Cython >= 0.29.21 when building for Python 3.9 and Cython >= 0.29.16 when building for Python 3.8. OpenBLAS >= 3.7 is needed to avoid wrong results on the Skylake architecture. The NumPy Wheels for this release can be downloaded from PyPI <https://pypi.org/project/numpy/1.19.1/>, source archives, release notes, and wheel hashes are available from Github <https://github.com/numpy/numpy/releases/tag/v1.19.1>. Linux users will need pip >= 0.19.3 in order to install manylinux2010 and manylinux2014 wheels. *Contributors* A total of 15 people contributed to this release.
