1. We need to explain the line: if __name__ == "__main__":

2. what does this mean? action="store_true"

3. (may be answer to question 2.) How do we tell it when it should expect a value after an argument and when it shouldn't? e.g. -t needs a value afterwards but -p doesn't.

This could do with some explanations and a link to the documentation (https://docs.python.org/3/howto/argparse.html#id1) or some examples.

For example, in addition to what Matthew suggests:

• what we are trying to do, and why it's a good idea to do it like this
• how to specify different arguments
• stress that the help is autogenerated (shown, but not described)

• Talk about 2 cases, run as a simple script vs as part of the library.
• Link to the documentation.
