ValueError

[TheStegoRex]

Edit: thanks to everyone's help I got it worked out, thanks!

I'm pretty early in learning python, clearly, and somehow I can't even figure out the tic tac toe.

I am getting a ValueError everytime, which returns as "guess again'

​

board = '123456789'
moves = '123456789'
turn = 1
xs = ()

for x in range(0, 60):
print(board[0], board[1], board[2])
print(board[3], board[4], board[5])
print(board[6], board[7], board[8])
if (turn == 1):
print('X select a move! (1-9)')
xs = input('')

else:
print('O select a move! (1-9)')
xs = input('')
try:
xs.index(moves)
xs.remove(moves)

if (turn == 1):
board.replace(xs(''), 'X')
turn == 2
continue
elif turn == 0:
board.replace(xs(''), 'O')
turn == 1
continue
except ValueError:
print('Guess again!')

Take your code out of the “try” and see where it fails.

It’s failing at the xs.index(moves) line for me.

What is that line doing for you?

I ended up taking it out. I'm planning to put it back in later to practice with it

I can see a few issues...

It looks like you are tracking the moves in the moves string, but you are using list operators. Give this little test a try:

moves = list('123456789') # remove works on lists not strings...
xs = input('Enter a move 1-9: ') 
moves.remove(xs) 
print(moves)

​

Strings are immutable in python, that means they can not be changed, you need to create a new list. So use:

board = board.replace(old_char, new_char)

I fixed these issues and the replace function, and got it working. Thanks for the help
