New issue 90 by
dwa...@translate.org.za: .add_mutually_exclusive_group()
only works when child of parser but not when a child of argument group
http://code.google.com/p/argparse/issues/detail?id=90
What steps will reproduce the problem?
parser = argparse.ArgumentParser()
group = parser.add_argument_group("Mutually exclusive group")
megroup = group.add_mutually_exclusive_group()
# megroup.add_argument() won't create mutually exlusive option.
megroup2 = parser.add_mutually_exclusive_group()
# Works as expected
What is the expected output? What do you see instead?
You should be able to create a mutually exclusive group as a child of an
argument group.
What version of the product are you using? On what operating system?
argpase 1.2.1
Please provide any additional information below.
Tested on Python 2.7 where this works correctly. The exact same code on
Python 2.6 with argparse 1.2.1 won't enforce mutual exclusion.
