Tic Tac Toe, Python, code won`t run

[deanhystad]

The positions are not empty when you start, they contain spaces.

Your game is hard to play. I didn't know how I was supposed to enter a position on the board. Do I enter row column or row, column or column, row or something else. Why do I have to enter two numbers? I don't like to type. Is the top left position 1, 1 or 0, 0?

There have been a lot of tic-tac-toe games on the forum and I like the ones that present the board like this:

Output:
1 2 3
4 5 6
7 8 9
Enter position (1-9) for X: 

It is pretty clear I should type 5 to put 'X' in the center position.

Using positions 1 through 9 also changes the board from a matrix to an array. And you don't have to worry about blank slots because the board starts out full.
