[issue30133] Strings that end with properly escaped backslashes cause error to be thrown in re.search/sub/etc. functions.

New submission from Patrick Foley: The following code demonstrates: import re text = 'ab\\' exp = re.compile('a') print(re.sub(exp, text, '')) If you remove the backslash(es), the code runs fine. This appears to be specific to the re module and only to strings that end in (even properly escap

R. David Murray added the comment: I think you are missing a re.escape around text. Text is otherwise not a valid replacement pattern. -- nosy: +r.david.murray ___ Python tracker _

[issue29903] struct.Struct Addition

STINNER Victor added the comment: I dislike this feature. I reject it: Serhiy, Raymond and me dislike it. I never needed this feature and a correct implementation can be very complex if you have to take care of endian, alignement, etc. It's trivial to implement you own add using the format att

[issue30075] Printing ANSI Escape Sequences on Windows 10

Terry J. Reedy added the comment: This is a (duplicate) enhancement request, not a bug report. The superseder field is for when an issue is closed as a duplicate; I decided that this should be. Further discussion should be on python-ideas. -- nosy: +terry.reedy resolution: -> duplic

[issue28041] Inconsistent behavior: Get st_nlink from os.stat() and os.scandir()

STINNER Victor added the comment: scandir () is designed for effiency, not for portability or correctness. The API has deliberate limitations which are well documented, as the one you spotted: https://docs.python.org/dev/library/os.html#os.DirEntry.stat Your PR would defeat the whole purpose o
