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

Function challenge says my function is failing, but it works perfectly in python shell

When I attempt the add_list challenge, it says it returns a value of None. However, when I use the python shell for add_list([1, 2, 3]) using the same code, I get a value of 6, which is expected. I also created a python script with the same code, and I get 6 as well. Am I not doing the challenge correctly?

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):
    for num in list:  
      total = num + num
    print (total)

Nevermind. I figured it out. I need to use return instead of print.
