My problem is that, in my game, each screen is 30x20, and I have

Using array of type H (16 bits per item = 2 bytes), my maps take just
6*2 = 120KB of memory.
Do you think I should still go with lists instead of an

Gives a pure linearization (you do the math for lines).
Do you mean : tilemap[(width*y)+x] ?
Yup, exactly.

Hi :)
First of all, I must apologize for my poor english :)
I'm starting with python and pygame and for testing (and learning)
purposes I wrote an small Map Editor for a small game project I'm
going to start next month.
The tilemap editor is working fine, but reading Guido's Van Rossum
