Don't add colon (:) for return statements.

I took your code and tried to understand the logic of if. Here is a reworked version: def sum_(a,b): if a==0 or b==0: return 0 else: return 1+sum_(a-1,b-1) print(sum_(4,2)) Please compare it with your code to find the amendments. Colonel Cop, I would recommend you to go through the python tutorial to get the basics. It' really worth to work on it.

Ok - so what is your question, or how can we help you? [ Edited]: There should no python function names and so on be used as identifiers. This can cause unexpected errors or results. Also indentation should be done properly.

Col. Any experience on recursion? Calling a function within itself? If not, let me tell you that you're using recursion here.
