I'm using the python optparse module in my program, and I'm having trouble finding an easy way to parse an option that contains a list of values.
For example:
--groups one,two,three.
I'd like to be able to access these values in a list format as options.groups[]. Is there an optparse option to convert comma separated values into a list? Or do I have to do this manually?
S.Lott's answer has already been accepted, but here's a code sample for the archives:
def foo_callback(option, opt, value, parser):
setattr(parser.values, option.dest, value.split(','))
parser = OptionParser()
parser.add_option('-f', '--foo',
type='string',
action='callback',
callback=foo_callback)
Look at option callbacks. Your callback function can parse the value into a list using a basic optarg.split(',')
