PDF generation issue: Error in Python docs
by Joakim Nybäck Jan. 1, 2021

Jan. 1, 2021

Hi, How to see the issue: 1. Open "library.pdf" (part of "python-3.9.1-docs-pdf-a4.zip" archive). 2. Search for the heading "strftime() and strptime() Format Codes". 3. Scroll to the end of the table; it is truncated. Also, the 8.1 heading is "superimposed" on the table towards the end, although it actually appears much earlier in this document. I have attached a screenshot of the issue. Best regards Joakim -- === MiniLockId === cQ29m7KMJJ1v64iYkbPu6v6LPbDVfNWen6C3EFme6Uinx

Documentation missing

Hello, It seems like nb_true_divide should map to both __truediv__ and __rtruediv__ but the latter is missing, in Type Objects — Python 3.9.1 documentation <https://docs.python.org/3/c-api/typeobj.html#tp-slots> Thank you!

[issue42781] functools.cached_property docs should explain that it is non-overriding
by Luciano Ramalho Jan. 1, 2021

Jan. 1, 2021

New submission from Luciano Ramalho <luciano(a)ramalho.org>: functools.cached_property is a great addition to the standard library, thanks! However, the docs do not say that @cached_property produces a non-overriding descriptor, in contrast with @property. If a user replaces a @property with a @cached_property, her code may or may not break depending on the existence of an instance attribute with the same name as the decorated method. This is surprising and may affect correctness, so it deserves even more attention than the possible performance loss already mentioned in the docs, related to the shared-dict optimization. In the future, perhaps we can add an argument to @cached_property to optionally make it produce overriding descriptors. ---------- assignee: docs@python components: Documentation messages: 384019 nosy: docs@python, ramalho priority: normal severity: normal status: open title: functools.cached_property docs should explain that it is non-overriding versions: Python 3.10, Python 3.8, Python 3.9 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue42781> _______________________________________
