1) Have you tested everything? At first glance some of those look like they
won't work.

2) Whenever you repeat yourself, *especially* at this magnitude, you're
doing something seriously wrong - *especially* in Python.

*Completely-untestedly-and-super-quick-hackedly:*

I wouldn't actually do it like this (I'd probably start with a dict and add
to a class programmatically), but this is a simple display of how one can
use classes and other meta-constructs to make things look nicer. It also
doesn't deal with forcing the number of arguments to be correct, but this
is demo material and so I leave that to you.
