the question is asking me to "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."
and this is my code
def add_list(number): return sum(number) def summarize(mylist): print("The sum of {} is {}".format(str(mylist), add_list(mylist)))
what am I doing wrong? I've run this in the workspace and it works, but it won't pass the challenge. Any help? Thank you.
# 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(number):
return sum(number)
def summarize(mylist):
print("The sum of {} is {}".format(str(mylist), add_list(mylist)))

The challenge specifically asks for a return and not a print statement at the end of the second function. I think you might want to try that.
