Return Statement in Python IDLE editor

[NMW]

Hi, I'm somewhat of a programming "newbie" , so bear with me.

I have been practising with Python (2) through Python IDLE. However, when I type code in the editor window and utilize a return statement, the return statement doesn't work after I run the code (there's no output in the shell window). Normally I would be able to type my code in the editor window, run it,and then get the results in the shell window.

However, when I type that same code in the shell window, and run the code, the return statement does work. How do I solve this? I want to be able to just type my code in editor mode, and then run.

def compare(x,y):
       if x > y:
               return 1
       if x == y:
               return 0
       if x < y:
               return -1

compare(5,7)
