I believe you want Python 3.7's parse_intermixed_args:
https://docs.python.org/3/library/argparse.html#argparse.ArgumentParser.parse_intermixed_args
A quick test seems to work:
import argparse
p = argparse.ArgumentParser()
p.add_argument('files', nargs='*')
p.add_argument('-f', '--force', action='store_true')
print(p.parse_intermixed_args())
$ python3 rm.py x -f y
Namespace(files=['x', 'y'], force=True)
$
