I've set up groups of arguments for a script I'm writing, and any time I
give an argument a value, it gets stored as a list instead of a string,
even if I explicitly tell it to store a string. Arguments declared with
other types (e.g. float, int) and default values are stored as expected.

The code using struct doesn't look terribly complicated, so that could
work. I might need to inspect other executable types, but I don't see it
I'm a bit new to programming outside of shell scripts (and I'm no expert
there), so I was wondering what is considered the best way to handle
errors when writing a module. Do I just let exceptions go and raise
custom exceptions for errors that don't trigger a standard one? Have the

Hi Andrew -
Sometimes you want an exception come up and then use that information to

You can raise an exception wherever you like! :-)
If I raise an exception that isn't a built-in exception, I get something
like NameError: name 'HelloError' is not defined. I don't know how to
define the exception.

Of course, there are all sorts of other things you could do with your
