You sure could, because functions are first order citizens in python,
meaning you can pass them around like any other data type.

menu['option 1']() is how you would call the functions, and you'd just put
an args/kwargs in the parenthesis.

Conceptually you can replace menu['option 1'] with f1, so anywhere you see
this:

menu['option 1'](arg1)

you can replace it with

f1(arg1)

I don't know if Python does that exact thing on the back end, but the end
result is certainly the same.

HTH,
Wayne
