declaimed the following:

>In C, C++, Ada, and functional languages, I can create an array of functions, albeit with the nastiness of pointers in the C family.   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.

>            r3c1   r3c2  r3c3

	Personally (and tied to Windows) -- I'd likely load the win32
extensions package and, since I do have M$ Office, programmatically create
that spreadsheet in a hidden Excel instance.

	Caveat: I've never actually done that... M$'s API has never felt
comfortable to me (I was spoiled by ARexx and applications with ARexx ports
on the Amiga).

	I don't know of any way to "magically" link your column three to using
arguments from the other two columns. Creating a table where each row is
two values and a function is no problem -- but I'd need to use external
code to run each row:

	results = [ f(x, y) for (x, y, f) in table]
