When I run parsePlotSens.py -s bw hehe
, it says that hehe
is an unrecognized argument. However, if I run parsePlotSens.py hehe -s bw
, it's OK. Ideally, I would like it work for both cases.
Any tips? The following is my code:
if __name__ == '__main__' :
parser = argparse.ArgumentParser(prog='parsePlotSens');
parser.add_argument('-s', '--sort', nargs =1, action = 'store', choices = ['mcs', 'bw'], default='mcs', help=sorthelp)
parser.add_argument('filename', nargs ='+', action = 'store')
option = parser.parse_args(sys.argv)
Do not pass sys.argv
as an argument to parse_args
. Just use
option = parser.parse_args()
If you do pass sys.argv
to parse_args
, then the path or name of the script itself is the first item in sys.argv
and thus becomes the value of option.filename
. The hehe
then becomes an unknown argument.
If you omit sys.argv
then parse_args
parses sys.argv
as expected.
