Total of a list

Write total(nums) returning the sum of a list of numbers, with a loop — sum() is off limits here. The total of an empty list is 0.

def total(nums):
    result = 0
    for n in nums:
        result = n
    return result

Run adds print(total([1, 2, 3])) after your code, to try it.

Stuck on the idea rather than the code? The Lists lesson walks through it.
