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

Help python function challenge

what i am doing wrong help me but dont show me the solution.

# 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(lst):
  for x in lst:
    total = sum(lst)
    return total
def summarize(strlst):
  for x in strlst:
    total = sum(strlst)
    return "The sum of"+" ".join(strlst)+"is:"+total

Hi there,

I recommend dropping the join method, and using curly braces to plug the values (specified as arguments of a format method for your string) into your return statement's string:

    return "The sum of {} is {}.".format(strlst,total)

Hope this helps!

You need to un-indent your return statements. They're inside of your for loops which means your loops won't be fully executed.
