What am I doing wrong here?

Here is what I have so far

ex_list = [1,2,3]

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

print(add_list(ex_list))

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

Hi Adrian,

It looks like two very minor issues:

  1. Your return statement is missing a closing parenthesis (note: you don't actually need parentheses around the return statement).

  2. "The sum of {} is {}" needs a period at the end.

When I run this against the code challenge, I get a syntax error because you're halfway using return like a function. Once that's cleaned up (remove the (), the first step passes. The second step fails because the string is slightly wrong.
