Rietveld is broken
by Andrew Svetlov 14 Nov '15

14 Nov '15

When I try to press 'retry' on http://bugs.python.org/review/25074/ page and send a message server responds with 500 error. Going through the page for viewing diff for concrete file http://bugs.python.org/review/25074/diff/15535/Lib/test/test_asyncio/test_b… with adding a comment works well. The behavior is very annoying -- I was forced to write missed message twice. -- Thanks, Andrew Svetlov

doc tests failing
by Ethan Furman 14 Nov '15

14 Nov '15

What am I doing wrong? I have tried: -------------------------------------------------------- hg update 3.5 # and hg update default make distclean && ./configure --with-pydebug && make -j2 cd Doc make doctest -------------------------------------------------------- and in both cases I get page after page of errors. I have tried installing python-sphinx and python3-sphinx; I have tried adding PYTHON=../python and PYTHON=python3 to the `make doctest` line -- all to no avail. Here's a random sample of the errors: ********************************************************************** File "library/shlex.rst", line ?, in default Failed example: remote_command Exception raised: Traceback (most recent call last): File "/usr/lib/python2.7/doctest.py", line 1315, in __run compileflags, 1) in test.globs File "<doctest default[1]>", line 1, in <module> remote_command NameError: name 'remote_command' is not defined ********************************************************************** File "howto/sorting.rst", line ?, in default Failed example: sorted([5, 2, 4, 1, 3], cmp=numeric_compare) Exception raised: Traceback (most recent call last): File "/usr/lib/python2.7/doctest.py", line 1315, in __run compileflags, 1) in test.globs File "<doctest default[1]>", line 1, in <module> sorted([5, 2, 4, 1, 3], cmp=numeric_compare) NameError: name 'numeric_compare' is not defined ********************************************************************** File "library/ipaddress.rst", line ?, in default Failed example: n2 = ip_network('192.0.2.1/32') Exception raised: Traceback (most recent call last): File "/usr/lib/python2.7/doctest.py", line 1315, in __run compileflags, 1) in test.globs File "<doctest default[1]>", line 1, in <module> n2 = ip_network('192.0.2.1/32') NameError: name 'ip_network' is not defined -- ~Ethan~

Translate Python language
by Christophe Bal 12 Nov '15

12 Nov '15

Hello. I'm a french teacher and I would like to use Python with young child but I've a big problem. All the keyword are in english. So I would like to know if there is a way to hack the AST tools such as to use french keywords and then translate a list of french keywords to their english regular version. Where should I start ? My idea is not to build a new language but simply translate words using an hacked version of the AST tools. Hoping to be clear and I do not pollute the message in this list. *Christophe BAL* *Enseignant de mathématiques en Lycée **et développeur Python amateur* *---* *French math teacher in a "Lycée" **and **Python **amateur developer*

modernizing IDLE
by Mark Roseman 11 Nov '15

11 Nov '15

Just wanted to share some documentation I’ve put together (and a snapshot of the code) on the effort to improve the appearance and behaviour of IDLE: http://www.tkdocs.com/tutorial/idle.html <http://www.tkdocs.com/tutorial/idle.html> (There’s also currently a post on Hacker News about this). While Terry can better speak to plans and timelines about getting these changes integrated in, it seems a good time to get some other people to have a closer look and share any feedback. Mark

[ANN] MicroPython 1.5
by Paul Sokolovsky 08 Nov '15

08 Nov '15

Hello, MicroPython is a lean and efficient Python implementation for microcontrollers, embedded, and mobile systems (which also runs just as fine on desktops of course). https://github.com/micropython/micropython Recent 1.5 release is an important milestone for the project, major changes including: 1. Advanced REPL support with smart auto-indent and auto-completion for comfortable interactive typing pf Python code, easily switchable to paste mode to copy pre-made code snippets. 2. Support for client SSL connections. 3. upip, MicroPython builtin package manager, is now fully standalone thanks to SSL support. 4. There's new, elaborated API to access hardware features ("machine" module). 5. There're now 2 well-supported microcontroller boards for MicroPython, and dozen(s) community-supported ones. 6. MicroPython was selected as one of the languages supported for BBC micro:bit initiative: http://ntoll.org/article/story-micropython-on-microbit 7. There's work on native efficient JNI bridge, inspired by Kivy's PyJNIus module, included into growing Android port. More detailed changelog for this version is at https://github.com/micropython/micropython/releases/tag/v1.5 MicroPython supports growing subset of Python3 standard library (including simplified asyncio package) - not included by default with an executable, but easily installable per-module using builtin "upip" package manager: https://github.com/micropython/micropython-lib -- Best regards, Paul mailto:pmiscml@gmail.com
