# Python Functions

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.

for item in list:
```

First, you need to initialize what total is. Second, you need to add the "item" to total.

For the summarize function, you just have to use your first function because it wants you to add a list. Then return the formatted string.

Here's my work:

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

P.S. there's a built-in function in python called sum(). It can take a list and return the sum. That's what I used when I was doing this challenge.

Here's my solution to challenge 1 & 2!

```def add_list(list):
total = 0;
for item in list:
total += item
