Sum of Integers - 'int' object is not iterable

Question

My question is related to the sum function in python.

So my code is

def black_jack(a, b):
    if sum(a, b) > 21:
        return 0
    else:
               


        

Answer 1

sum expects iterable object (like list). So the code should be:

def black_jack(a, b):
    if sum([a, b]) > 21:
        return 0
    else:
        return sum([a, b])

print black_jack(10, 5)
