[issue40127] Documentation of SSL library
by Christophe Nanteuil April 4, 2020

April 4, 2020

New submission from Christophe Nanteuil <christophe.nanteuil(a)gmail.com>: For the ssl.create_default_context() function, it states that, "if cafile, capath and cadata are None, the function *can* choose to trust the system's default CA certificates instead". This statement is not clear as, if the values are None, there is no choice and the only elements available are system's default CA. AFAIK, if the values are not None, it will not fall back to system's default CA even if the given CA … [View More]

[issue40131] Zipapp example has parameters in the wrong order
by Leron Gray April 3, 2020

April 3, 2020

New submission from Leron Gray <daddycocoaman(a)gmail.com>: The second example listed here for zipapp has the parameters in the wrong order. https://docs.python.org/3/library/zipapp.html?highlight=zipapp#examples It should be create_archive("myapp", "myapp.pyz") since the parameters are (source, target). The documentation for the function itself is correct though. ---------- assignee: docs@python components: Documentation messages: 365436 nosy: Leron Gray, docs@python priority: … [View More]

Bug in documentation of mailbox.Maildir
by Stefan Witzel April 3, 2020

April 3, 2020

Hi, I think there is a bug in the documentation of "class mailbox.Maildir". If the dirname path exists it will be accepted as a Maildir directory. If the dirname path not exists and create is True a new Maildir directory will be created, otherwise the interpreter raises a mailbox.NoSuchMailboxError exception.

Official Documentation Error on Nan
by arnuld April 3, 2020

April 3, 2020

Hi There, You are receiving email because it was written at the bottom of this page: https://docs.python.org/3/reference/expressions.html I think I found a documentation error (bug?) . In section "6.10.1. Value comparisons", it is written: "The not-a-number values float('NaN') and decimal.Decimal('NaN') are special. Any ordered comparison of a number to a not-a-number value is false. A counter-intuitive implication is that not-a-number values are not equal to themselves. For example, if x = … [View More]

Possible issue in string formatting
by Shlomo Gottlieb April 3, 2020

April 3, 2020

Hi, I noticed that when using string format to print hexadecimal numbers like the following: *>>> '{:#X}'.format(1234)* *'0X4D2'* I get an uppercase 'X' which in my opinion should remain lowercase 'x' (like: *'0x4D2'*) If you think it should be like it is today all uppercase then I'd suggest to add it in the docs. Today the docs state (here <https://docs.python.org/3/library/string.html#string-formatting>): 'X' Hex format. Outputs the number in base 16, using upper-case … [View More]

[python problem]pyinstaller GUI exe error
by kiho kim April 3, 2020

April 3, 2020

Hello python developers. I'm having a problem with GUI operation, so I send a bug mail. The code developed by pycharm was converted to exe and executed, but the message 'Failed to execute script (file name)' appears and ends. To test for any problems, when an exe conversion is performed to an empty GUI window without any function, it works normally, but importing obspy causes the same error. I used commands like pyinstaller, cx_freeze, py2exe, etc. to fix the error, I also formatted Windows OS, … [View More]

Bug reporting
by Eşref Yiğitbaşı April 3, 2020

April 3, 2020

Hello, my name is Esref Yigitbasi. Me and my friend Talha Demirsoy found a bug on python. We wrote a function that finds how many zeros are at the end of the number. If we enter the number up to 24 digits, the program gives correct results but after 25 digits it always gives wrong results. The function we wrote is as follows; *counter = 0number = 1000000000000000000000000while True: if number % 10 == 0: counter += 1 number = number / 10 else: breakprint(counter)* … [View More]
