Optparse Python Set Boolean

boolean, optparse, python

Solution

You have the return values reversed:

(args, opts) = parser.parse_args()

should be

(opts, args) = parser.parse_args()

Everything will then work.

Problem

I'm having a ton of trouble getting optparse to work in python. It is my first time using it, so any help would be greatly appreciated. I read through all the documentation, but even with their examples, it is not working for me. I am trying to use --clean to make a boolean variable equal to true. This is what I have: ``` desc = "Use this script for fun!" parser = optparse.OptionParser(description=desc) parser.add_option('--clean', help='Run cleaner option', dest = 'runclean', default = False, action = 'store_true') (args, opts) = parser.parse_args() print opts.runclean ``` I thought this would set runclean to true, but when I do: ``` print opts.runclean ``` I get: ``` AttributeError: 'list object has no attribute 'runclean' ``` Any ideas?
