A recent post recommended the docopt module so I've incorporated it

the code I'm using to learn SQLite. It's not behaving as I expected.
Here's a snippet of code:
#!/usr/bin/env python
# -*- coding : utf -8 -*-
# file: 'test'
"""Usage: test [new_data | text_entry FILE | show_data ] [-hdv]
[--db=DATABASE] [--tb=TABLE]
-h --help show this
-d --debug show debugging statements
-v --verbose shows table when not absolutely necessary.
--db DATABASE specify database file to use [default: ./uwomeds68.db]
--tb TABLE specify table to use [default: matesTb]
"""
You have no definitions for new_data, text_entry, FILE and show_data,
and the use of the square brackets around them looks wrong.
What I believe I'm specifying here is that these are mutually exclusive
commands, one of which must be entered. This part is behaving properly.
If you haven't already looked at them there are lots of extremely
useful examples here
https://github.com/docopt/docopt/tree/master/examples.
Thanks, yes, I've been looking there. What I haven't been able to
create is an example of my own where a default value is specified in the
Usage pattern and gets propogated into the dictionary created by docopt.
I haven't yet given up.
