Dear Maintainer, I think the failure is a direct consequence of [1]. argparse module in Python 3.13 modified argument parsing from the command line.
foo.py script: import argparse parser = argparse.ArgumentParser() parser.add_argument('-v', '--verbosity', default=0, type=int, choices=[0, 1],) parser.print_help() $> python3.12 foo.py usage: foo.py [-h] [-v {0,1}] options: -h, --help show this help message and exit -v {0,1}, --verbosity {0,1} $> python3.13 foo.py usage: foo.py [-h] [-v {0,1}] options: -h, --help show this help message and exit -v, --verbosity {0,1} Kind Regards [1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1082209
