Average of a list

Return the mean of a list: the total divided by how many numbers there are.

len(nums) tells you how many items the list has. Dividing with / always gives a decimal, so the average of 1 and 2 is 1.5.

Write average(nums) that returns the mean: the total divided by how many numbers there are. The list is never empty.

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