Potential typo in Profiler docs?
by 2dfkit 09 Nov '23

09 Nov '23

In the[profiler docs](https://docs.python.org/3/library/profile.html), under the first profiler output example, it says > ... The next line:Ordered by: cumulative time, indicates that the text string in the far right column was used to sort the output. This doesn't appear to make sense, and indeed the example output is sorted by the "cumtime" column, and not by the text string column at the far right. Am I misreading this or is this a typo? Thanks! PS. Sorry I didn't raise a ticket, I'm new and shy about posting in public forums

about deprecated document
by SUN Guonian 09 Nov '23

09 Nov '23

hi, When I browse subprocess document on (https://docs.python.org/3.11/library/subprocess.html) I find some piece about "Replacing os.popen(), os.popen2(), os.popen3()", but I can't find any popen3() in module os, untill I search the document to version 2.7. Maybe the content related to the deprecated document should be cleaned in the latest version. Best Regards, SUN Guonian

Problem in help for str().rsplit()
by Alan Brogan 09 Nov '23

09 Nov '23

Greetings to the list Not sure where this report should be sent, so I’m hoping the good people on this list can help to forward it on. The docs suggest I should distinguish a bug as being either of the docs, or of the implementation, but this one is in the docstring of the function, so which does that count as??? What I would call "the docs” (https://docs.python.org/3/library/stdtypes.html?highlight=rsplit#str.rsplit <https://docs.python.org/3/library/stdtypes.html?highlight=rsplit#str.rsplit>) explains the function differently, and is (AFAICT) correct Problem is in docstring for the str().rsplit() method: >>> help(str().rsplit) Help on built-in function rsplit: rsplit(sep=None, maxsplit=-1) method of builtins.str instance Return a list of the substrings in the string, using sep as the separator string. sep The separator used to split the string. When set to None (the default value), will split on any whitespace character (including \\n \\r \\t \\f and spaces) and will discard empty strings from the result. maxsplit Maximum number of splits (starting from the left). -1 (the default value) means no limit. Splitting starts at the end of the string and works to the front. Problem is at the phrase "(starting from the left)” I think that should actually say “starting from the right”, because >>> s = "alan was here today" >>> s.rsplit(" ", 1) ['alan was here', 'today'] -- Alan

Errors in 3.11.4 EPUB version
by Ranjith B 09 Nov '23

09 Nov '23

Dear Python community, The EPUB version for 3.11.4 is not readable. Each page contains errors like the following: “This page contains the following errors: error on line 22 at column 19: Specification mandates value for attribute defer Below is a rendering of the page up to the first error.” Please fix the issue. Thank you, Best Regards, Ranjith

bug reports for the documentation (mainly the tutorial)
by Stephan Stiller 30 Oct '23

30 Oct '23

Dear list, I recently read through the entire Python tutorial and FAQ (v3.11.2) and took notes on things that I believe to be errata. Here is my list: 1. https://docs.python.org/3/tutorial/controlflow.html I think it would be better if there were a pastable space after "144 233 377 610 987 1597" (and in some other places in the tutorial). My guess is that the present formatting has to do with the way these pages are generated. 2. https://docs.python.org/3/library/stdtypes.html#dict.get I think "get(key[, default=None])" would be better than "change get(key[, default]). 3. https://docs.python.org/3/library/stdtypes.html#mapping-types-dict It seems that "sorted(d)" is missing from the documentation, at least on this page. The output (sorted list of all keys) is not predictable for a beginner, so it might be better to be explicit. 4. https://docs.python.org/3/tutorial/modules.html About the instruction for loading "fibo" ("Now enter the Python interpreter and import this module with the following command:"): Many beginners will be using IDLE. If on Windows, one needs to import the file like this: import sys sys.path.append(r'C:\path_to_directory_with_fibo') import fibo Adding a remark like this will help the reader. 5. https://docs.python.org/3/tutorial/inputoutput.html The '{:-9} YES votes {:2.2%}'.format(yes_votes, percentage) example will slow a careful first-time reader down. I suggest explaining the two expressions in curly braces briefly on the side, in one sentence each. 6. https://docs.python.org/3/tutorial/inputoutput.html#old-string-formatting I would replace the second sentence by something like the following For the expression "format % values", "%" conversion specifications in "format" are replaced with zero or more elements of "values". or something similar adapted from here: https://docs.python.org/3/library/stdtypes.html#old-string-formatting 7. https://docs.python.org/3/library/functions.html#open I strongly suggest replacing "buffering=- 1" by "buffering= -1". I suspect this might be a systematic bug generated by a formatter. Similarly, here https://docs.python.org/3/library/stdtypes.html#str.split I would replace "str.split(sep=None, maxsplit=- 1)" by "str.split(sep=None, maxsplit= -1)". In both cases, deleting the space entirely is an alternative option. 8. https://docs.python.org/3/tutorial/errors.html#exceptions If I understand correctly, I believe it will be clearer if "and execution stops with a message as shown above" is shortened to simply "and execution stops". 9. https://docs.python.org/3/faq/extending.html#how-do-i-extract-c-values-from… "PyListSize()" should probably read "PyList_Size()". General comments: I believe that a HOWTO on "object-oriented programming" best practices in Python would be useful. Perhaps there is one, but I couldn't find it. Best regards, Stephan Stiller

https://docs.python.org/3/library/timeit.html
by Goldberg, Arthur P 30 Oct '23

Hello In this section This is a convenience function that calls timeit()<https://docs.python.org/3/library/timeit.html#timeit.Timer.timeit> repeatedly so that the total time >= 0.2 second, returning the eventual (number of loops, time taken for that number of loops). It calls timeit()<https://docs.python.org/3/library/timeit.html#timeit.Timer.timeit> with increasing numbers from the sequence 1, 2, 5, 10, 20, 50, … until the time taken is at least 0.2 second. s/second/seconds/ two times. “seconds” is properly plural elsewhere on the page.

Howto/regex omits the simplest {n} case
by Derek Mead 30 Oct '23

30 Oct '23

Hi, https://docs.python.org/3/howto/regex.html#repeating-things states: *You can omit either m or n; in that case, a reasonable value is assumed for the missing value. Omitting m is interpreted as a lower limit of 0, while omitting n results in an upper bound of infinity.* This is correct, for the cases of {m,} and {,n}. What isn't covered is the simplest case {m} which matches the preceding item exactly m times. Regards, Derek PS https://docs.python.org/3/howto/regex.html is generally one of the best bits of software documentation I have come across: it's a model of simplicity and clarity, on a notoriously difficult topic.

We need a new coordinator for Simplified Chinese translation
by alphanow＠foxmail.com 01 Aug '23

01 Aug '23

Hi WG members, Hope you all are well. I'm writing this email to ask for help, as the sync pipeline for Simplified Chinese document translations has been broken for a long time. The workflow is hosted on GitHub Action(https://github.com/python/python-docs-zh-cn/tree/master). And its last success was already 8 months ago(https://github.com/python/python-docs-zh-cn/actions?query=is%3Asuccess+…. Our contributors have prepared a fix for the workflow. However, we cannot reach out to the current maintainer of this repo to merge it. And we have tried to ask in the translation mail list (https://mail.python.org/archives/list/translation@python.org/thread/YOPHUNQ…), but it seems there is no response. So, would you like to assign a new coordinator or maintainer for the repo? Then we can work together to fix the issue. Thx & B.Rgds Du, Meng
