TIC TAC TOE game

anyone here done a tic tac toe game on python before ?
i need help on how to start this thing. so far i've made the grid.

print "TIC TAC TOE:"
print "0|1|2 | | "
print "----- -----"
print "3|4|5 | | "
print "----- -----"
print "6|7|8 | | "

i only know to keep doing if statements to put where the X and O's would be. but that would be toooooooo much coding. so i need a really shorter way to put the marks where the user tells me to put them.

how about using a list to represent each position of the board, considering that you already have them numbered? then just print out the other characters with the elements of the list concatenated in?

general syntax for lists:

Code:

listvar = [element1, element2, element3, element4, ...]
valueOfElementX = listvar[X]
firstThreeElements = listvar[:3]

et cetera...

so far this is the code i have

Code:

def drawBoard(marks):
    """ Output the board represented by marks."""
    print "TIC TAC TOE:"
    print "0|1|2      | | "
    print "-----     -----"
    print "3|4|5      | | "
    print "-----     -----"
    print "6|7|8      | | "
    return drawBoard

def setPosition(marks):
    """sets the positions to given player's mark."""
s=str(drawBoard)
marks=s[0],s[1],s[2],s[3],s[4],s[5],s[6],s[7],s[8]
drawBoard("X XOXOXO ")

i have made a string named marks that is suppose to be the positions of the X's and O'x on the board. now is i want an X in for example in marks[0]. What command could i add to put the X there ?

consider the following:

Code:

def drawBoard(marks): 
    """ Output the board represented by marks."""
    print "TIC TAC TOE:"
    print "0|1|2     "+marks[0]+"|"+marks[1]+"|"+marks[2]
    print "-----     -----"
    print "3|4|5     "+marks[3]+"|"+marks[4]+"|"+marks[5]
    print "-----     -----"
    print "6|7|8     "+marks[6]+"|"+marks[7]+"|"+marks[8]
    return drawBoard
    
marks = ["X", " ", " ", "O", "X", "O", "X", "O", " "]

drawBoard(marks)

marks[2] = "X"

drawBoard(marks)

I'm sorry, but I'm not going to write the entire program for you. Look into the raw_input() and int() functions.

i know those commands. but i don't know how to call it from a function.
i have this
[CODE]
def drawBoard(marks):
""" Output the board represented by marks."""
print "TIC TAC TOE:"
print "0|1|2 "+marks[0]+"|"+marks[1]+"|"+marks[2]
print "----- -----"
print "3|4|5 "+marks[3]+"|"+marks[4]+"|"+marks[5]
print "----- -----"
print "6|7|8 "+marks[6]+"|"+marks[7]+"|"+marks[8]
return drawBoard

marks = [" ", " ", " ", " ", " ", " ", " ", " ", " "]

drawBoard(marks)

def setPosition(i, string, marks):
""" Sets the positions of the strings """
if i == 0:
marks = string+marks[1]+marks[2]+marks[3]+marks[4]+marks[5]+marks[6]+marks[7]+marks[8]
if i == 1:
marks = marks[0]+string+marks[2]+marks[3]+marks[4]+marks[5]+marks[6]+marks[7]+marks[8]
if i == 2:
marks = marks[0]+marks[1]+string+marks[3]+marks[4]+marks[5]+marks[6]+marks[7]+marks[8]
if i == 3:
marks = marks[1]+marks[2]+marks[3]+string+marks[4]+marks[5]+marks[6]+marks[7]+marks[8]
if i == 4:
marks = marks[0]+marks[2]+marks[3]+marks[4]+string+marks[5]+marks[6]+marks[7]+marks[8]
if i == 5:
marks = marks[0]+marks[1]+marks[3]+marks[4]+marks[5]+string+marks[6]+marks[7]+marks[8]
if i == 6:
marks = marks[1]+marks[2]+marks[3]+marks[4]+marks[5]+marks[6]+string+marks[7]+marks[8]
if i == 7:
marks = marks[0]+marks[2]+marks[3]+marks[4]+marks[5]+marks[6]+marks[7]+string+marks[8]
if i == 8:
marks = marks[0]+marks[1]+marks[3]+marks[4]+marks[5]+marks[6]+marks[7]+marks[8]+string

def playerTurn(marks):
"""ask the user where they want to move."""
marks=setPosition(i,marks)
return playerTurn

i=str(raw_input("Player X, choose where you want to make your mark: "))
setPosition(i, str, marks)
print drawBoard
[CODE]

i have tried
[CODE]
def playerTurn(marks):
a=str(raw_input("Player X, select the position that u want/
insert your X: "))
return playerTurn
[CODE]
but that doesn't work, its not like that i'm not trying anythin, its just that i couldn't get it, and that's y i'm asking for your help. And i thank you a lot for helping me so far already.

Ok, a few things.

1. You do not always need to return a value from a function. For instance, drawBoard() does not need to return anything - it just displays output.

2. Your setPosition function is overly complicated. How about the simple

Code:

def setPosition(num, string, marks):
    marks[num]=string
    return marks

3. To have the user input a number, try

Code:

num = int(raw_input("Please enter a number:"))

4. Put any code you post inside CODE and /CODE (not two CODE) tags. Otherwise indentation doesn't show up, which is critical for python.

This is the code i have right now. its suppose to ask user for position to place the X or O, (playerTurn function) then with the setPosition function, the X or O should be placed in. then with the updated marks, print the new grid.

Code:


def drawBoard(marks): 
    """ Output the board represented by marks."""
    print "0|1|2     "+marks[0]+"|"+marks[1]+"|"+marks[2]
    print "-----     -----"
    print "3|4|5     "+marks[3]+"|"+marks[4]+"|"+marks[5]
    print "-----     -----"
    print "6|7|8     "+marks[6]+"|"+marks[7]+"|"+marks[8]
    return drawBoard

def setPosition(i, string, marks):
    """ Sets the positions of the strings """
    if i == 0:
        marks = string+marks[1]+marks[2]+marks[3]\
        +marks[4]+marks[5]+marks[6]+marks[7]+marks[8]
    if i == 1:
        marks = marks[0]+string+marks[2]+marks[3]\
        +marks[4]+marks[5]+marks[6]+marks[7]+marks[8]
    if i == 2:
        marks = marks[0]+marks[1]+string+marks[3]\
        +marks[4]+marks[5]+marks[6]+marks[7]+marks[8]
    if i == 3:
        marks = marks[0]+marks[1]+marks[2]+string\
        +marks[4]+marks[5]+marks[6]+marks[7]+marks[8]
    if i == 4:
        marks = marks[0]+marks[1]+marks[2]+\
        marks[3]+string+marks[5]+marks[6]+marks[7]+marks[8]
    if i == 5:
        marks = marks[0]+marks[1]+marks[2]+marks[3]\
        +marks[4]+string+marks[6]+marks[7]+marks[8]
    if i == 6:
        marks = marks[0]+marks[1]+marks[2]+marks[3]\
        +marks[4]+marks[5]+string+marks[7]+marks[8]
    if i == 7:
        marks = marks[0]+marks[1]+marks[2]+marks[3]\
        +marks[4]+marks[5]+marks[6]+string+marks[8]
    if i ==8:
        marks = marks[0]+marks[1]+marks[2]+marks[3]\
        +marks[4]+marks[5]+marks[6]+marks[7]+string
    return marks
    


def playerTurn(s, marks):
    """  when given the players symbol (X or O), asks the player for his or her choice.
    It should then put the the players mark on the board. """
    
    if s == "X":
        x= int(raw_input("Player X, choose where you want to make your mark (0-8): "))
        if x>=0 and x<=8: 
            marks = setPosition(x, "X", marks)
            return marks

s="X"
marks="         "

print "TIC TAC TOE:"
drawBoard(marks)
playerTurn(s, marks)
drawBoard(marks)

you need to change one line:

Code:

playerTurn(s, marks)

should be

Code:

marks = playerTurn(s, marks)

also, i'd highly recommend using a list instead of a string for marks, which then allows the shorter

Code:

def setPosition(num, string, marks):
    marks[num]=string
    return marks

as it's much more consise. if you do that, the overall program becomes the (much shorter):

Code:

def drawBoard(marks): 
    """ Output the board represented by marks."""
    print "0|1|2     "+marks[0]+"|"+marks[1]+"|"+marks[2]
    print "-----     -----"
    print "3|4|5     "+marks[3]+"|"+marks[4]+"|"+marks[5]
    print "-----     -----"
    print "6|7|8     "+marks[6]+"|"+marks[7]+"|"+marks[8]
    return drawBoard

def setPosition(num, string, marks): 
    marks[num] = string
    return marks

def playerTurn(s, marks): 
    """  when given the players symbol (X or O), asks the player for his or her choice.
    It should then put the the players mark on the board. """
    
    if s == "X": 
        x = int(raw_input("Player X, choose where you want to make your mark (0-8): "))
        if x >= 0 and x <= 8: 
            marks = setPosition(x, "X", marks)
            return marks

s = "X"
marks = [" ", " ", " ", " ", " ", " ", " ", " ", " "]

print "TIC TAC TOE:"
drawBoard(marks)
marks = playerTurn(s, marks)
drawBoard(marks)

mmm

Mybe the best way is to do it VB style and create a nice user interface first, then create an AI if you want to after.
