why doesn't this code work to return the sum of the list

num_list = [1,2,3]

def add_list(num_list):
    s=0
    for x in num_list: 
        s +=x
                print(s)

add_lis(num_list)

When I run this script in OSX terminal I get the printed sum after each iteration. How can I make it print only the total sum?

Looks like your print statement is nested within the for loop. Try moving it back out to the same indentation level as the s= and for loop lines.
