That part is not considered a loop.

There is a type of programming paradigm called "recursion" that is 
similar to loops, perhaps that's what you're thinking of?

def recursive_sum(num):
    if num == 0:
        return 0
        return num + recursive(num - 1)

 >>> recursive_sum(15)
 >>> sum(range(16))

However your example is not recursion, because the function does not 
call itself repeatedly; rather, call_numbers is called once, and then it 
repeatedly calls a _different_ function.  Savvy the difference?
