Yes that can all work.

Consider using a dictionary keyed by your combined choice values.
Then the big if/elif chain shrinks to
returnValue = FuncDict[choice](params)
The only challenge with this route is making all the functions
take a single input argument. But that argument can be a tuple :-)

Try putting it on the pastebin web site and sending us the URL.
That gives us colour coding of syntax too which helps read it!
