How to get list out of argument space
# 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.

You should do a for loop to get the each value of the list and do the sum of each one and then return it at the end. It should look like this:
def add_list(a_list):
sum = 0
for item in a_list:
sum = sum + item # is the same as sum += item
return sum
As a piece of advice, always use lowercase letters for everything except when defining classes (use just 1 uppercase letter at the beginning)
Hope this helps :)

I would take a look at this post to see if it helps. I thought it offered a good explanation.
Happy coding,
