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

So confused about this objective. What am I supposed to do, and where to start?

Make a function named add_list that takes a list. The function should then add all of the items in the list together and return the total. Assume the list contains only numbers. You'll probably want to use a for loop. You will not need to use input().

functions.py
# 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.

hi, here is the solution. and some discuss before.

https://teamtreehouse.com/community/make-a-function-named-addlist-that-takes-a-list-i-am-stuck-help

mylist = [1, 2, 3]

def add_list(mylist):
    total = 0
    for number in mylist:
        total = total + number
    return total

add_list(mylist)

if still confuse, visualization showing a Python program will help you.

just paste this code and see every step how it works. :)
