what did i do wrong here?

# add_list([1, 2, 3]) should return 6
def add_list (number):
    total = 0
    for item in number:
      total = item + item
    return total
# summarize([1, 2, 3]) should return "The sum of [1, 2, 3] is 6."
def summarize (number):
  print ("The sum of {} is {}".format(number, add_list(number)))
# Note: both functions will only take *one* argument each.

Your summarize() function should return, not print().

is this the right way?

def summarize(number): return "The sum of {} is {}".format(number, add_list(number))

Yes, that should pass except I think it might need a period at the end of the string.
