Array of Functions

I second the call for a more concrete implementation, but if you want the results of the functions in c3 to be responsive to the values of c1 and c2 (i.e., if you change r1c1, r1c3 returns a different value), it might be worth encapsulating the whole thing in an object and making the c3 functions properties, which is Python for 'preprocessed attributes.'

For example, an array of functions where each function is an active button, or an array of functions that behave like formulae in a spreadsheet.  I am finding this a bit challenging in Python.

Suppose I want an array where the colum three is a set of functions that operates on the other two columns, depending on the values I set for those rows and columns?    As noted, I can do this pretty easily in most languages (well, except for Java which does not support any kind of functional programming capability), even if I have to use pointers.
