challenge task 2 of 2

I run the task 2 on workspace successfully. But the challenge always give me an error.. Can somebody help me? Thank you.

# 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(arr):
  total = 0
  for a in arr:
    total += a
  return total

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

hie there.

you should return that string and not print it, just replace your print with return and it will work out fine. the syntax is correct that's why it runs on workspaces but it wont pass the challenge because the challenge is hard coded to accept return as stated in the task.

don't forget to remove the extra pair of parenthesis(outer braackets) when you remove print.
