`xrange()` doesn't return a generator or iterator

I think that was thoughtlessly rude to somebody who is asking a perfectly
reasonable question.

Hello everyone,
I was wondering if anyone here has a moment of time to help me with 2
things that have been bugging me.
1. Multi dimensional arrays - how do you load them in python
For example, if I had:
---
1 2 3
4 5 6
7 8 9
10 11 12
13 14 15
16 17 18
---
with "i" being the row number,
31 matches
