[issue43713] sorted() signature is not accurate in the documentation
New submission from Tomer Kalish : According to the docs, the sorted function's signature is: sorted(iterable, *, key=None, reverse=False) But when printing its help interactively, the signature is: sorted(iterable, /, *, key=None, reverse=False) The latter seems to be the correct one, as calling sorted(iterable=arr) will raise a TypeError. The signature in the docs should be fixed. -- assignee: docs@python components: Documentation messages: 390122 nosy: docs@python, tomer.kalish91 priority: normal severity: normal status: open title: sorted() signature is not accurate in the documentation type: resource usage versions: Python 3.10, Python 3.6, Python 3.7, Python 3.8, Python 3.9 ___ Python tracker <https://bugs.python.org/issue43713> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue37831] bool(~True) == True
New submission from Tomer Vromen : Bitwise operators have inconsistent behavior when acting on bool values: (Python 3.7.4) # "&" works like "and" >>> True & True True >>> True & False False >>> False & False False # "|" works like "or" >>> True | True True >>> True | False True >>> False | False False # "~" does not work like "not"! >>> ~True -2 >>> ~False -1 The result of this is the a user might start working with "&" and "|" on bool values (for whatever reason) and it will work as expected. But then, when adding "~" to the mix, things start to break. The proposal is to make "~" act like "not" on bool values, i.e. ~True will be False; ~False will be True. I'm not sure if this has any negative impact on existing code. I don't expect any, but you can never know. If there is no objection to this change, I can even try to implement it myself an submit a patch. -- components: Interpreter Core messages: 349452 nosy: tomerv priority: normal severity: normal status: open title: bool(~True) == True type: enhancement versions: Python 3.7 ___ Python tracker <https://bugs.python.org/issue37831> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue36913] Missing documentation for decorators
Tomer Vromen added the comment: Thank you for the quick response. Are PEPs considered de-facto documentation for language features? For example, string formatting was described in PEP 3101, but still has sections in the documentation dedicated to it. I believe that decorators should get a similar treatment :-) I also think that describing decorators as part of the grammar definition is lacking. Why is there a whole chapter for Errors and Exceptions and it's not only discussed under the grammar definition for raise? Decorators are a pretty unique (and cool!) feature of Python, and therefore new learners of the language need a better reference for learning about them. I realize that this is a big request, as you would need some expert to write this documentation. -- ___ Python tracker <https://bugs.python.org/issue36913> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue36913] Missing documentation for decorators
New submission from Tomer Vromen : The documentation for decorators (for methods and classes) is pretty lacking. Searching for "decorator" ( https://docs.python.org/3/search.html?q=decorator ) brings up a lot of libraries that use decorators, but no documentation explaining what they are and how they work. The documentation should have a dedicated page for explaining decorators, and this should be the 1st search result. -- In the meantime, then search should give as a 1st result a link to the definition of decorator in the glossary: https://docs.python.org/3.7/glossary.html#glossary Actually, it seems that there is no way to directly link to a paragraph in the glossary - so that should be added as well. In general, it would be nice if a search for some term X would show as a 1st result the definition of X in the glossary (if it exists there).

[issue34439] Expose venv --prompt value to an environment value
New submission from Tomer Keren : In the same way the $VIRTUAL_ENV variable tells the virtual environment directory, A variable such as $VENV_NAME or $VENV_PROMPT should tell the value given to the venv `--prompt` option (Introduced in Issue22829). An individual could override the EnvBuilder class like the docs say, but that wouldn't insure any user will have the variable set. This is crucial for usage in custom libraries that want to display the given prompt. -- components: Library (Lib) messages: 323782 nosy: Tomer priority: normal severity: normal status: open title: Expose venv --prompt value to an environment value type: behavior versions: Python 3.5, Python 3.6, Python 3.7, Python 3.8 ___ Python tracker <https://bugs.python.org/issue34439> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18225] ctypes Structure data size is incorrect
New submission from Tomer Levi: Whenever you create a ctypes.Structure with mixed ctypes, the size of all components is calculated by the size of largest one. This is especially irritating when trying to use Structure on bytearray.
