这是我使用 Python 创建的这个 TIC TAC TOE 游戏。

import os
os.system('cls')

i = 0
#Exiter
def exithoja():
    import sys
    raw_input
    sys.exit()

#Displays Win or Draw
def diswin(name,grid):
    i = checkwin(grid)
    os.system('cls')

    viewgrid(grid)

    if i ==1:
        print name, " has won the game !!"
    elif i == -1:
        print "This Match is a draw !!"
    exithoja()
#Checking for Win or Draw Function
def checkwin(grid):
    i = 0
    result = 0
    extra=0
    for i in range (1,9):            #This part checks for full grid.
        if (grid[i] == 'X' or grid[i]=='O'):
            extra += 1
        if (grid[1] == grid[2] and grid[2] == grid[3]):
            result = 1                   #This part checks for win.

        elif(grid[4] == grid[5] and grid[5] == grid[6]):
            result = 1
        elif(grid[7] == grid[8] and grid[8] == grid[9]):
            result = 1

        elif(grid[1] == grid[4] and grid[4] == grid[7]):
            result = 1

        elif(grid[2] == grid[5] and grid[5] == grid[8]):
            result = 1

        elif(grid[3] == grid[6] and grid[6] == grid[9]):
            result = 1

            result = -1

    return result         #0 for continue,1 for win, -1 for draw.


#Grid Print Function
def viewgrid(grid):
    print "\n\n      .       .\n",

#Grid Print Function Ends

        if markgrid('O',grid,i) == 0:

        player12(i,grid,name1)
        i = checkwin(grid)
        print i
        if i==1 or i == -1:
            diswin(name1,grid)
        player2(name2)
        return grid
    def player2(name2):
        i = player21(name2,grid)
        if markgrid('X',grid,i) == 0:

        player22(i,grid,name2)
        i = checkwin(grid)
        if i==1 or i == -1:
            diswin(name2,grid)
        player1(name1)
        return grid
    player1(name1)
    player2(name2)
    return grid
#Main Program end

#Main Program Execution
grid = []

grid = playgame()

剩下的主要事情是只接受函数 player11 和 player21 中变量“place”的整数。如果它不是整数，则将再次调用该函数并为“place”分配新值。请帮助我如何去做......在此先感谢......编辑：用户/播放器不会被给予任何错误代码......

根据寻求宽恕比请求许可更好的原则，我会用一个简单的 try:except 子句来做到这一点

while True:
    r = raw_input('choose ')
    try:
        c = int(r)
    except ValueError:
            print 'Not valid.\n'
    else:
        break
        #This will be executed only if no exception is raised

print c

注意：else: break只有在没有引发异常时才会执行。因此，如果您输入的不是整数，则会引发异常，该else:break子句将不会被执行，它不会中断循环，并且会要求再次插入一个数字。如果您插入一个数字，则不会引发异常，'else:break'将执行并退出 while 循环，您的数字仍存储在变量 c 中
