# Function Challenge Task 1 of 2

Hi Python community,

Can I have someone provide any insight on this challenge involving returning a list of numbers that equals 6 in a list? I've already defined my list with a num argument and I was in the process of using the "for" loop as an index to sum the numbers together, but I keep getting a syntax error. Any advice would be appreciated!

Martel

functions.py
```def add_list(num):
for i = 1:1:7
```

The return of 6 was just a specific example in the case that the list [1, 2, 3] was passed in as the argument. What the challenge wants you to do is provide a generic solution to summing all numbers in a list. The list will be provided when your code is being checked.

To start, you'll want a variable local to the function that will keep track of the sum. Then you will want to use a for loop to iterate over all the numbers in the list. The for loop follows the pattern:

```for item in collection:
#...
```

So in order to get all the numbers out of the list and add them you'll want to do something like this:

```for number in number_list:
#Update sum here.
```

Then finally return the sum.
