[issue24446] imap and map inconsistent behaviour

Ned Deily added the comment: This is a documented behavior difference in itertools.imap: If function is set to None, then imap() returns the arguments as a tuple. Like map() but stops when the shortest iterable is exhausted instead of filling in None for shorter iterables. The reason for the

[issue24447] tab indentation breaks in tokenize.untokenize

New submission from Dingyuan Wang: If a script uses tabs for indentation, tokenize.untokenize won't restore original indentation correctly from the second line of the indentation level, and thus breaks the file. This affects all Python versions. Test code: python2 -c 'import sys, tokenize;

Martin Panter added the comment: The 3.5 documentation of str.strip() was recently modified in Issue 24204 due to this kind of misunderstanding. Perhaps other versions should be modified as well, or the str.l/rstrip() methods, or the bytes() and bytearray() methods. See also Issue 23560

[issue24412] setUpClass equivalent for addCleanup

R. David Murray added the comment: Not having addClassCleanup means that my setUpClass method will have four try/excepts in it, as will my tearDownClass (I have four fixtures I'm setting up for the tests). So, no, it isn't strictly needed, but it is prettier :). As Robert says, though, it

[issue24412] setUpClass equivalent for addCleanup

Serhiy Storchaka added the comment: addCleanup() is helpful because it can be used in test methods. addClassCleanup() and addModuleCleanup() can't be used in test methods, and setUpClass() and setUpModule() are used less than setUp(), therefore the benefit of these methods are less than of
