I am adding one more testcase in order to clarify more the problem:
import argparse
import sys
parser = argparse.ArgumentParser(prog=sys.argv[0], add_help=False)
parser.add_argument('-a', action='store_true')
parser.add_argument('-b', action='store_true')
parser.add_argument('-c', action='store_true')
parsed_args, unknown_args = parser.parse_known_args(sys.argv[1:])
print(parsed_args)
print(unknown_args)
$ python argparse_test.py -ab
Namespace(a=True, b=True, c=False)
[]
Expected result:
$ python argparse_test.py -ab -cd
Namespace(a=True, b=True, c=True)
['-d']
Actual result:
$ python argparse_test.py -ab -cd
usage: argparse_test.py [-a] [-b] [-c]
argparse_test.py: error: argument -c: ignored explicit argument 'd'
