Your function has input argument numberList but refers to it as floatNums (a variable that is defined in another post therefore outside the scope of your function). There will never be a division by zero because the interpreter will not be able to proceed to the division.

pk is right, python has a built in sum() function, although his code example is sloppy.
def mean(nums):
if len(nums):
return float( sum(nums) / len(nums))
else:
return 0.0

couldnt you just do

def mean(numberList):
return float(sum(floatNums)) / len(numberList)
