More Python problems!

No idea why the code below will not work for the challenge I am on?

def summarize(list_of_numbers):
  counter = 0
  for item in list_of_numbers:
    counter = counter + item
  num_to_str = print str(list_of_numbers)
  sum_of_list = print str(counter)
  return("The sum of {} is {}.".format(num_to_str, sum_of_list)

Remove those print statements, just assign the values directly to num_to_str and sum_of_list and you'll be fine, I think.

def summarize(list_of_numbers):
  counter = 0
  for item in list_of_numbers:
    counter = counter + item
  num_to_str = str(list_of_numbers)  ## Now you're assigning the value to the variable
  sum_of_list = str(counter)               ## instead of printing it!
  return "The sum of {} is {}.".format(num_to_str, sum_of_list)

Also be sure to enclose the return statement in the right number of parentheses. Remove the leading ( or add one at the end of the return statement (it isn't necessary)

That should give your return statement the right values.
