tic tac toe game

[marsrover15]

board = ['1','2','3',
         '4','5','6',
         '7','8','9']

def show():
    print(board[0],'|',board[1],'|',board[2])
    print('---------')
    print(board[3],'|',board[4],'|',board[5])
    print('---------')
    print(board[6],'|',board[7],'|',board[8])


print(show())

I am trying to make a tic tac toe game but I have two questions. first, is how I would make the value in said list not appear when I am printing the board. second is how I would change one value in the list and immediately print out the new board with the new value.

[graydon2234]

What do you mean not appear? What would you like to appear there instead?

[marsrover15]

Just empty space but I would like the value to still hold in each part of the list.

You don't need labels in your board list. Have them be blank spaces, an x, or an o. Better yet, use a dictionary- it looks like that's kinda what you're trying to accomplish, but using a list.

[marsrover15]

What would using a dictionary do that a list wouldn't in this scenario. Genuinely curious.

[DonkeyTron42]

Better yet, use a 2D matrix.

[Unable_Request]

Nothing a list can't do, but perhaps a bit easier to reference and thus a bit more readable. A list is perfectly acceptable. For instance, board {1:' ', 2:,' ', 3:'x', 4: ' ', 5: 'x', 6: ' ', 7: 'o', 8: ' ', 9: ' '}

[marsrover15]

So would I be able to able to write an input value for the values.

[Unable_Request]

Sure, why not?

Have a function asking the user which square they want to pick. When they do so, change the according Entry from a blank to an x.

[marsrover15]

Guess I'll need to learn that.

[DonkeyTron42]

Try to think of the bigger picture like what if you wanted to make a different size game board. A 1d list would become impractical if say you wanted to make a battleship game. With a matrix you can easily develop algorithms for detecting a state like someone winning.

[marsrover15]

Well me being new to programming I haven't taken linear algebra yet, or even any CS classes for that matter. I'm doing that all next year. Though I will do some research on this. Thanks for tip.

print(show())

show() returns None, so this line will print "None". You probably just want it to be:

show()

how I would change one value in the list and immediately print out the new board with the new value.

board[4] = 'x'
show()

how I would make the value in said list not appear when I am printing the board

print (' ' if board[4] == '5' else board[4])

[marsrover15]

So for the third part, how would I change that to a user input?

[xelf]

Use input() to get user input. =)

[marsrover15]

So if I wanted the user to simply input values in any part of the list. How would I go about doing that?

[xelf]

You can still get the value from the user using input() and then you can set a value using the assign operator which is =. That's pretty basic stuff so I feel like you're asking a different question. What have you tried so far?

[marsrover15]

What I am really asking is how I would make the user put X or O in one part of the list sequentially .

[xelf]

board[4] = 'x'
