Python Python Basics (Retired) Putting the "Fun" Back in "Function" Functions

How do you complete this challange?

You can find my code attached. When I do task 2, it says task 1 is no longer passing. I don't understand what the problem is the least bit.

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(something):
  return sum(something)

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

You'll want to drop the call to print and just return the formatted string. print doesn't return any value.

I have tried that previously with no luck. I'll drop it again. While call to print is a problem it doesn't seem to be the main problem here.

Looks like you were missing an extra parenthesis. format and sum were closed but not print so maybe the mismatch remained after you dropped it the first time.

I checked it again to be sure and this passed:

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