[issue13720] argparse print_help() fails if COLUMNS is set to a low value

Yeah, the whole example with IDLE is moot: argparse only checks
$COLUMNS and defaults to 80, so if COLUMNS is not set, you are only
checking if the code works with 80 columns.

Please try my commandline example or set os.environ['COLUMNS'] = 15.
I get the exception in IDLE too.
