Python Python Basics (Retired) Putting the "Fun" Back in "Function" Functions

Is var1 not a global variable once it has been returned from add_list(list)?

I thought that if the value was returned, it should be able to be used in the output of the print() statement in the second task.

Here's what I came up with, that's clearly not working:

list = [1,2,3] def add_list(list): var1 = 0 for num in list: var1 = var1 + num return var1

def summarize(list): var2 = str(list) print("The sum of {} is {}.".format(var2, var1)

You are trying to access var2, which is within the scope of the add_list function. In order to use the value of var2, you need to call the function that returns it.

Also, the code challenge is asking you to return the string, not print it.

Try this:

list = [1,2,3]
def add_list(list):
    var1 = 0
    for num in list:
        var1 = var1 + num
    return var1

def summarize(list):
    var2 = str(list)
    return "The sum of {} is {}.".format(var2, add_list(list))

Hope that helps!
