Why won't this pack?

def new(*args):

total = 0
for thing in args:
    total += thing
print(total)

x = (1,2,3)

y = (4,5,6)

new(x,y)

Why won't this pack? Help appreciated.

Hi Youssef,

You've declared x as a tuple (1, 2, 3). Also, you've declared y as a tuple (4, 5, 6). Therefore you are passing two arguments into your function, both tuples. You've declared total as an int (0). You can't add a tuple to an int.

What you can do is unpack x and y into their individual elements when you call the function (so in effect you are passing six arguments into your function, all ints):

new(*x, *y)

Hope that helps,

Alex
