for x,y in (range(3),range(3)):
    print(x+','+y)

I wont a simple output of any pare of numbers something like that:

1,1
2,2

I get:

    for x,y in (range(3),range(3)):
ValueError: too many values to unpack (expected 2)

kederrac :

you can use the built-in method zip:

for x,y in zip(range(3),range(3)):
    print(x, y, sep=',')
