Python的argparse可以用一组选项替换单个选项吗？

import argparse

parser = argparse.ArgumentParser()
group = parser.add_mutually_exclusive_group()

group.add_argument('-a', action='store_true', help='Option A')
group.add_argument('-b', action='store_true', help='Option B')
group.add_argument('-c', action='store_true', help='Option C (combination of A and B)')

args = parser.parse_args()

if args.a:
    print('Option A selected')
elif args.b:
    print('Option B selected')
elif args.c:
    print('Option C selected (combination of A and B)')
else:
    print('No option selected')
