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

Stuck after first line. I have def add_list(a,b,c): as my first line of code but I'm unsure what to do after that.

Hey I've looked at this for a while now so any help would be greatly appreciated. I know the syntax I need to use to start the function I just don't know how to plug in numbers for the variables I created and I have no Idea why I would need a for loop for this exercise.

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.
def add_list(a,b,c):
  summarize = a+b+c

Your problem is that you assumed they would enter in the list manually but really they are passing in a list, so instead you should change your arguments to take in a list.

def add_list(list):
    summarize = 0
    # A for loop that loops through all of the items in the list and adds each one to summarize
    return summarize

Hopes this helps you out!
