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

WHAT DID I DO WRONG

functions.py 
def add_list(lst) :
  result = 5
  for item in lst:
    result += item 
    return result
  def summarize(lst) :
    X = list
    Y = add_list(list)
    resut = "the sum of {}".format(X, Y)

It looks likes a few things could be improved:

  1. def summarize(lst): needs to be outdented to the same level as def add_list(lst)
  2. summarize() needs a return resut statement.
  3. format() arguments need to match the number of targets "{}". You need another "{}"

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

def summarize(list):
    X = list
    Y = add_list(list)
    result = "The sum of {} is {}".format(X, Y)
    return result

your result was wrong, You did resut and you didn't add 2 curly brackets to replace X and Y
