SMTPHandler secure argument without credentials
by William Edwards 15 Sep '22

15 Sep '22

logging.handlers.SMTPHandler only uses the 'secure' argument when credentials are specified. https://docs.python.org/3/library/logging.handlers.html#logging.handlers.SM… says: "To specify the use of a secure protocol (TLS), pass in a tuple to the secure argument. This will only be used when authentication credentials are supplied." The docstring confirms this, but I can't find an explanation of the intent behind this behaviour. Perhaps it would be a good idea to describe this as well.

epubs don't work on google play
by Trenton D. Adams 31 Mar '22

I don't know why, but your EPUB of python docs at https://docs.python.org/3.8/download.html or https://docs.python.org/3/download.html cannot be processed after uploading to google play books. This is very unfortunate. :( I really like using my android phone for reading stuff.

Docs for the multiline string with an initial escape is not correct in version 3.3+
by Martin Bendsöe 23 Mar '22

23 Mar '22

This is correct: https://docs.python.org/3.2/tutorial/introduction.html Or, strings can be surrounded in a pair of matching triple-quotes: """ or '''. End of lines do not need to be escaped when using triple-quotes, but they will be included in the string. So the following uses one escape to avoid an unwanted initial blank line. print("""\ Usage: thingy [OPTIONS] -h Display this usage message -H hostname Hostname to connect to """) This is NOT correct: https://docs.python.org/3.3/tutorial/introduction.html String literals can span multiple lines. One way is using triple-quotes: """...""" or '''...'''. End of lines are automatically included in the string, but it’s possible to prevent this by adding a \ at the end of the line. The following example: print("""\ Usage: thingy [OPTIONS] -h Display this usage message -H hostname Hostname to connect to """)

Possible typo in https://docs.python.org/3/tutorial/classes.html
by Lyle Ziegelmiller 22 Mar '22

22 Mar '22

Hi https://docs.python.org/3/tutorial/classes.html A sentence reads, "Clients should use data attributes with care - clients may mess up invariants maintained by the methods by stamping on their data attributes." I think it should be, "Clients should use data attributes with care - clients may mess up invariants maintained by the methods by stomping on their data attributes.".

Typing information in collections.abc documentation
by Harry Lees 10 Mar '22

10 Mar '22

Hi, more recently when I've been using Python, I've been trying to annotate my code with type hints. Unfortunately, I'm not always 100% sure about how to properly annotate code using the typing module so I find myself frequently going back to look up the syntax. I'm aware that since PEP 585, many of the generic functions that used to reside in typing should now be replaced with the collections.abc alternatives. Unfortunately, most of the information that I find helpful about these type hints are still in the typing module, I often find myself looking up the annotation I want in collections.abc, realising its not there and then going back to the typing docs. I was wondering if it would be appropriate to have some of that information transferred across to the collections.abc module, or at least some reference to the typing documentation where applicable. For example collections.abc.Generator, if I wanted to add a type hint for this, the typing documentation gives a great overview: "A generator can be annotated by the generic type Generator[YieldType, SendType, ReturnType]". From what I can tell, this information is nowhere to be found in the collections.abc docs, there isn't even a mention that it could be annotated in that way apart from the "New in version 3.9" section near the top of the page. Thanks, Harry.

Improvements to the sys.path initialization documentation
by Russel Webber 07 Mar '22

07 Mar '22

Hi All, Steve Dower, Eryk Sun and I have been working on improving the documentation around how sys.path is initialised and therefore how Python modules are found. We're moving the details from https://docs.python.org/3.11/using/windows.html#finding-modules to a platform-agnostic new section in https://docs.python.org/3.11/using/cmdline.html We're aiming to have one place in the documentation where all the ways to customize sys.path (PYTHONPATH, ._pth, site, etc) are at least mentioned. We'd appreciate further community feedback on the changes before they are merged. https://bugs.python.org/issue31582 https://github.com/python/cpython/pull/31082 Thank you, Russel

potential bug in python 3
by Ali Arslan 06 Mar '22

06 Mar '22

Hi we just noticed there is a potential bug in for loop variable assignment in for loop. variable must unset after the block end at least in other programming language they do but in python 3 last assignment still exist sorry for my bad English but I can tell you with an example for i in range(3): print(i) out put is 0 1 2 but if you call i again print(i) output 2 I don't know it is by purpose for some reason but I haven't seen it in any source so most of the programmers don't handle this situation . this situation can cause over ram usage and it might effect program's efficacy and optimization in large scale programs such as games or data processing if programmers don't handle this situation . Thanks Ali ARSLAN
