# Could someone point me in the right direction...

I'm an task 1/2. I can make a function, but forgot how to ass lists. Could someone nudge me in the right direction.

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.

``` MOD
1. Add together list items using built-in function
```result = sum( list )
```

2.Loop over items and add them to subtotal:

```result = 0
for item in list:
result += item
```

You will also need to have an argument in your function: `def add_list(arg):`

Combining all of this, you would have something like this:

```def add_list(arg):
result = sum(arg)
return result
```

or combining the last two statements:

```def add_list(arg):
return sum(arg)
```

It's not really working. I don't think I fully get what your saying.

That really helped, thanks! Could you take a look at the second challenge. Here's my code. What arguments do I pass to .format

''

# Note: both functions will only take one argument each. The first argument would be the `arg2`. The second argument would be the sum which can be written as `add_list(arg2)`. Putting those together you get:
```def summarize(arg2):
