# function

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().

add_list ([1, 2, 3])

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.
print(1+2+3)

add_list ([1, 2, 3])
```

Currently, your function takes a list but doesn't use it. Also, to call the "add_list" function you made you can just type in the name of the list into the parentheses.

```num_list = [1, 2, 3]

total = 0
for num in num_list:
total = total + num
```

That should get you through the first half of the challenge.

I have done with this:

Code #1:

```def add_list (list):
total = 0
for i in list:
total += i
```def summarize(list):
