I've been learning Python lately, and I thought I should let everyone take a look at a very primitive program that I did. I thought that maybe it could help a few newbies, eh? Since I'm used to C, it uses a list within a list to simulate a two dimmensional array.

/msg Nanosecond with bugs.

"""Tic Tac Toe v0.2 by Nanosecond in 2001 in Python

	-TODO: Add a second method for Connect 4 like play
	-TODO: Make it so not entering input doesn't crash it
	-TODO: Make it so entering non-integer input doesn't crash it
	-TODO: Figure out why NE to SW doesn't work
	-TODO: Figure out why doesn't detect win if height, width, and row are equal
