Hello, KanZen!

Python doesn't have multidimension arrays. It has only sequences and dicts
which consist from values indexed by keys. When you write a[1,2,3] python
always see a[key] where key=(1,2,3). Tuples created automaticly where
neccessary. Try "return 1, 2, 3" or "a,b,c = 1, 2, 3" statements.

With best regards, Alexander Semenov.
