#file: argp.py

import argparse

parser = argparse.ArgumentParser(prog='PROG')
parser_subparsers = parser.add_subparsers()
sub = parser_subparsers.add_parser('sub')
sub_subparsers = sub.add_subparsers()
sub_sub = sub_subparsers.add_parser('sub_sub')                                                                       
sub_sub_subparsers = sub_sub.add_subparsers()
sub_sub_sub = sub_sub_subparsers.add_parser('sub_sub_sub')

Seems to work.

In [392]: run argp.py

In [393]: parser.parse_args('sub sub_sub sub_sub_sub'.split())
Out[393]: Namespace()

In [400]: sys.version_info
Out[400]: sys.version_info(major=2, minor=7, micro=2, releaselevel='final', serial=0)
