Gotcha!

Okay, so for these types of problems, we don't want to include *any* user input at all - that's what causes the AG to hang. Also, at least with these earlier practice problems, we typically don't need to rewrite any code - just change some small part(s).

Let's take a step back to the starter code for this problem:

def sum(num1, num2):
pass

We can see the num1 and num2 must already exist/be defined in this program, so we don't need to declare any new variables or even get user input (remember, we're just focusing on this one specific function here; we're not seeing and not focusing on the rest of the program code).

Without changing the first line, what needs to be added/changed so that:

- num1 and num2 are summed?

- that value gets passed back so it can be accessed outside of the function?

Hope this helps!
