You have two for loops that have nothing inside of them.

Also, you don't have + between your strings in that last print() function (and you shouldn't have a space between print and the parentheses).

Hi Anthony

The return and print lines should be indented further as they are statements of their respective for loops.

Weirdly when I've tried to run it however it doesn't return the correct value and fails on the first task which is confusing as you already seem to be onto the second one.

Here's my code for the first task which will hopefully help you through the second. You create a method that takes a list as an argument, loops through each number in the list adding them together then returns the final value.

def add_list(list):
  total = 0
  for num in list:
    total += num
  return total

Hope it helps!
