def add_list(lists): print (sum(lists))
why is this code not accepted? I've tested it in python 3.4
# 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(lists):
print (sum(lists))

Print is not equal to return.
your last line should look more like.
def add_list(lists):
answer = (sum(lists))
return answer
print add_list([1,2,3,4])

Your function needs to return a value.
def add_list(lists):
return sum(lists)
