# Code Challenge 2 of 2 help

I am obviously not understanding the way the question is asked, here's my code: def add_list(list): sum=0 for items in list: sum=sum+items return(sum)

def summarize(list): return("The sum of {} is {}".format(list, sum))

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.

sum=0
for items in list:
sum=sum+items
return(sum)

def summarize(list):
return("The sum of {} is {}".format(list, sum))
```

Looks like you almost had it. You should avoid using python keywords such as "list" for your variables and args. I've used test_list in place of list in your code.

for summarize you need to change to: return "The sum of {} is {}".format(test_list, add_list(test_list))

You don't need a parenthesis around what you are returning, so you can just delete them and return the string with the `.format()` call attached.
Next, the second term of the `.format()` call needs to be a call to `add_list(list)`, and not the variable `sum`; `sum` doesn't exist as far as the second function is concerned, it exists entirely within `add_list()`. Notice, however, that sending `list` to `add_list()` is going to return the `sum` of said list, which is why it serves your purposes there.
