def average(numbers):
total = sum(numbers)
total = float(numbers)
total % len(numbers)

Here you go I have comment this code. Try an see if you can understand it and play arround with it

``````def average(numbers):
#first total is 0
total = 0
#loop through numbers
for i in numbers:
#add each value to the total
total += i
#convert total to float and return it
return float(total)/len(numbers)``````

In the instructions it says to use the Sum() function. Why Didn't you use it? is it easier to just use the += operator?

@james1468 yes you can also use the sum function like below. As to which method to use it depend on the programmer. Although I guess the sum function gives you much less code to write

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

the change you need to make in yours is to change the `% to /`
