Tuple index out of range

Question

print "\n\t\t\t\t",moves[6],"|",moves[7],"|",moves[8]

IndexError: tuple index out of range

is the error that I am getting. I am currently writing a python program for tictactoe. moves is equal to ['','','','','','','','','']. Would you like any other info?

I have so far, changed 789 in the row to 678 because indexes begin at 0. Nothing happening.

Next, I tried various other small changes, each of which either changed the error or just gave me the same error.

I also attempted to change formats and things, which did not go so well. I am running python 2.7(?), if that matters.

Answer 1

Line 14:

moves = ['','','','','','','','','']

Line 192:

moves = XorO(player, ai)
...

    draw(moves)

You overwrote your initial declaration of moves, so ('X', 'O') is being passed to draw.

Answer 2

The only tuple I see in the code is ways. Also you don't seem to initialize new before you use it in the function 'win'. FYI, tuples are made using parentheses tup = (1, 2, 3, 4) while lists use brackets list = [1,2,3,4]. Tuples are also immutable, so you can't modify them later.

Answer 3

If moves is ['','','','','','','','',''] and the error message you're getting is:

IndexError: tuple index out of range

Then the error is not occurring on the line you say it is. moves is a list, not a tuple. And it does have indices up to 8. moves[9] would generate this error instead:

IndexError: list index out of range
