The argparse module for Python 2.7 includes a command line help option, that by default prints a usage message whenever -h or --help is present in the command line options. By default, the help option can be passed in with any other command line options. For example:
script.py [-h] [-opt1 arg1 | -opt2 arg2]
If the -h optional argument exists, all other args are ignored and the help message is printed.
Is there a way to change this behavior so that -h has to be used alone, like can be done with any other optional arg by placing it within a mutually_exclusive_group?
