I am very lost, I don't feel like this question was addressed in the previous videos. I don't know how to make a function take a list and I'm not sure exactly what this question is asking me to do. Do I create a list containing 1, 2 and 3, as in: my_list = [1, 2, 3] and then create a 'for' loop as in: 'for item in my_list', and then add each number up inside the loop during each iteration? I've been spending hours on this and haven't been able to get anywhere. I saw from a previous question on this topic that you can use the built in sum() function to add up all the items in the list, but don't understand how a user function would be needed if i can just add everything up with a built-in function. Any help would be appreciated.

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.
my_list = [1, 2, 3]

my_sum = int(0)
for item in my_list:
my_sum = my_sum + item

print(my_sum)
```

# Note: both functions will only take one argument each.

my_list = [1, 2, 3]

```for item in my_list:
my_sum = my_sum + item

return my_sum
```

# you can print my_sum from the function or return the value then print the function using ```def add_list(list1):
