code returns the wrong value...

My code returns 2 instead of 6 and I dont see why... Help!

functions.py 
# add_list([1, 2, 3]) should return 6
# summarize([1, 2, 3]) should return "The sum of [1, 2, 3] is 6."
# Note: both functions will only take *one* argument each.

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

whitespace matters! (in Python anyway).

You have indented your 'return sum' statement. It prematurely exits the for loop after the first iteration.
