984 PointsI am trying to use the " ".join method on a list of numbers, and its not working. help?
what should I do in order to go from [3,2,5] to "3 2 5", for example. Thanks.
# 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(x):
total = 0
for y in x:
total = total + y
return total
def summarize(x):
total = add_list(x)

However, you can do
# convert list to string
str([2,3,4]) #=> "[2, 3, 4]"
this should be enough to help you solve the problem.

984 PointsThanks! But how do i convert [3,4,3] to "3 5 6" (not "[2,5,2]")

Courses Plus Student 26,868 PointsI failed to see why you wanna convert it to 3 5 6, the example output of summarize is "The sum of [1, 2, 3] is 6." converting the list to 3 5 6 doesn't help you in implementing the summarize function, it will in fact make it a lot more difficult.

984 Pointsok, now i see. thanks a lot!

Courses Plus Student 26,868 Pointsyes, depending on how you format that string, if you wanna combine them using +, you have to use str() for the list, otherwise
def summarize(x):
return "The sum of {} is {}.".format(x, sum(x))
