Mutually exclusive options with argparse.

See the following code snippets [1] for implementation of the exclusive options with argparse:

def query_builder(args):
if args.r and args.s:
sys.exit(Term.FAIL + 'Only one of -re and -sql should be set' + Term.ENDC)
sum_status = sum(1 for x in [args.failure, args.code != -1] if x)
if sum_status > 1:
sys.exit(Term.FAIL + ('Only one of --failure and --code has to be set') + Term.ENDC)

It seems that the above method is awkward, but I'm out of idea to work out more graceful solutions. Any comment/suggestion/enhancement will be highly appreciated.

Does a mutually exclusive group, as described in "Mutual exclusion" at
https://docs.python.org/3/library/argparse.html meet your needs?

Thanks for letting me know about this feature. I'll give it a try.
