how to put a list in a function

I don't understand how to put a list as an argument in a function.

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.

I've only had VERY BASIC exposure to Python so I don't know if this is the BEST way to send a list to a function but it works:

# add numbers
numberList = [1, 2, 3]

def add_numbers(numbers):
    return sum(numbers)

print add_numbers(numberList)

You can paste the code here, click the save icon, then click "execute" to verify

good luck!

Also, FYI, if you use the Python v3.3 compiler on that site you have to use parenthesis with print. The version above uses v2.7

print( add_numbers(numberList) )
