Comma separated inputs instead of space separated inputs for argparse

Question

I\'m using argparse to receive inputs from the command line to run my script.

My current input string looks like this:

path> python &

If you're okay with space not comma separated, then it's builtin to argparse:

In [1]: from argparse import ArgumentParser

In [2]: parser = ArgumentParser()

In [3]: parser.add_argument('-a', nargs='+')
Out[3]: _StoreAction(option_strings=['-a'], dest='a', nargs='+', const=None, 
                     default=None, type=None, choices=None, help=None, metavar=None)

In [4]: parser.parse_args(['-a', 'foo', 'bar'])
Out[4]: Namespace(a=['foo', 'bar'])
