[New-bugs-announce] [issue15929] argparse non alphanum characters replacement

[Julien Castets]

New submission from Julien Castets:

argparse.add_argument replaces dashes with underscores. If an argument contains another non alphanum character, accessing to it will result to a syntax error.

#! /usr/bin/env python

import argparse

if __name__ == '__main__':
    argParser = argparse.ArgumentParser()
    argParser.add_argument('--foo+', action='store_true')
    arguments = argParser.parse_args()

    print 'getattr foo+: %s' % getattr(arguments, 'foo+') # ok
    print arguments.foo+ # syntax error

The patch replaces every non alnum character with an underscore.
