Now, make a function named summarize that also takes a list. It should return the string "The sum of X is Y.", replacing "X" with the string version of the list and "Y" with the sum total of the list

Below is my code please help

functions.py 
list= [1, 2, 3]
list= [1, 2, 3]
def summarize(list):
  total = 0
  for item in list:
    total += item

  return total

print("The sum of"+' '+str(list)+' '+'is'+' '+str(summarize(list))+".")

# summarize([1, 2, 3]) should return "The sum of [1, 2, 3] is 6."
# Note: both functions will only take *one* argument each.

[edit formatting --cf]

You have all the pieces they just need to be rearranged. It looks like you renamed the add_list() function to summarize()

Change the name back to add_list(), then create an addition function named summarize() that calls add_list and uses the result to populate the string from your print statement. Lastly, summarize should return the formatted string instead of printing it.

def add_list(something):
  result = 0
  for item in something:
    result += item
  return result

def summarize(something):
  return "The sum of " + str(something) + " is " + str(add_list(something)) + "."
