One thought.. Perhaps when you introduce OOP, you could rewrite this
as a subclass of the class in the cmd module. It would simplify your
code quite a bit, I think... You'd be able to do stuff like:

calc> 5
5
calc> add 5
10
calc> sub 2
8
calc> help
==============================
commands:
==============================
add       sub     mul     div
calc> help add
...
