Does anybody know if there is a way to specify groups of mutually exclusive options using argparse module?
Currently argpase allows to specify mutually exclusive options in the following way (taken from https://docs.python.org/release/3.4.0/library/argparse.html#argparse.ArgumentParser.add_mutually_exclusive_group ) >>> parser = argparse.ArgumentParser(prog='PROG')>>> group = >>> parser.add_mutually_exclusive_group()>>> group.add_argument('--foo', >>> action='store_true')>>> group.add_argument('--bar', >>> action='store_false')>>> parser.parse_args(['--foo'])Namespace(bar=True, >>> foo=True)>>> parser.parse_args(['--bar'])Namespace(bar=False, foo=False)>>> >>> parser.parse_args(['--foo', '--bar'])usage: PROG [-h] [--foo | --bar]PROG: >>> error: argument --bar: not allowed with argument --foo What I need is a way to specify groups of mutually exclusive options. In other words >>> parser = argparse.ArgumentParser(prog='PROG')>>> group1 = >>> parser.add_argument_group()>>> group2 = parser.add_argument_group()>>> >>> group1.add_argument('--foo', action='store_true')>>> >>> group1.add_argument('--bar1', action='store_false')>>> >>> group2.add_argument('--foo2', action = 'store_true') >>> group2.add_argument('--bar2', action = 'store_false') >>> mutually_exclusive_group = parser.add_mutually_exclusive_argument_group() >>> mutually_exclusive_group.add_group(group1) >>> mutually_exclusive_group.add_group(group2)>>> parser.parse_args(['--foo1', >>> '--bar1', '--bar2'])usage: PROG [-h] [--foo1, --bar1] | [--foo2, >>> --bar2]PROG: error: argument --foo1 or bar1 not allowed with argument >>> --foo2 or bar2
