Python code returns “None”

Question

def average(numbers):
    total = float(sum(numbers))
    total /= len(numbers)
    return

Error: Oops, try again.

average([3, 0]) returned None instead of 1.5 as expected.

What is wrong pls?

Answer 1

You are not returning any value.

Try this instead:

def average(numbers): 
    total = float(sum(numbers)) 
    total /= len(numbers) 
    return total
