It might help a little if you made it more obvious which was line 23 ...

The real problem, though, is a misunderstanding of what getopt.getopt()
returns. The (option, value) pairs are only returned for options found
in the command line, so you can't guarantee there'll be four.

Set your values to defaults, then adjust for those for which an option
is found in the list, as in the "typical usage" example in the Fine Manual.
