Martin Panter added the comment: See duplicate Issue 22363 for the traceback, and a workaround. There is also a patch there similar to Garrett’s original fix, but using the RE r'%s *%s ?'.
I restored the diff from Garrett’s repository, in case it is still useful. Yogesh: I am not familiar with how the code works, and I struggle to be excited at using regular expressions to build a usage message :). But can you explain why you changed Garrett’s original fix? Does it affect intentional double spaces (or tabs, non-ASCII spaces, etc) in customizable parts of the usage message? ---------- nosy: +martin.panter stage: -> patch review title: argparse: mutually exclusive groups full of suppressed args can cause AssertionErrors -> argparse: mutually exclusive groups full of help-suppressed args can cause AssertionErrors _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17890> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
