我使用Python 3创建了一个Noughts和Crosses的多人游戏。 除了检查循环之外，我已经完成了所有代码。
每次输入新符号时，如果是获胜的移动或者电路板已满，则检查循环将被输入。 目前，我的代码在一个玩家连续输入3个符号或者电路板变满后才能完成。
到目前为止，这是我的代码：
import random
def start_player():
startplayer = random.randint(1,2)
if startplayer == 1:
turn = 'X'
print("Player One (X) will start the game.")
else:
startplayer == 2
turn = 'O'
print("Player Two (O) will start the game.")
return turn
def getmove():
row = int(input("Please enter a number between 0 and 2: "))
column = int(input("Please enter a number between 0 and 2: "))
while grid[row][column] != "":
print("Invalid move.")
row = int(input("Please enter a number between 0 and 2: "))
column = int(input("Please enter a number between 0 and 2: "))
return row, column
def mainturn(row, column):
global countmove
countmove = countmove + 1
global symbol
grid[row][column] = symbol
for y in range(0,(len(grid))):
print(grid[y])
if symbol == 'X':
symbol = 'O'
elif symbol == 'O':
symbol = 'X'
return countmove
def check_win(row, column, symbol):
if (grid[0][0] and grid[0][1] and grid[0][2] == symbol) or (grid[1][0] and grid[1][1] and grid[1][2] == symbol) or (grid[2][0] and grid[2][1] and grid[2][2] == symbol) or (grid[0][0] and grid[1][0] and grid[2][0] == symbol) or (grid[0][1] and grid[1][1] and grid[2][1] == symbol)or (grid[0][2] and grid[1][2] and grid[2][2] == symbol)or (grid[0][0] and grid[1][1] and grid[2][2] == symbol) or (grid[2][0] and grid[1][1] and grid[0][2] == symbol):
print("Well done!",symbol," won the game.")
return true
elif countmove == 9:
print("Board Full. Game over.")
#main program
grid = [["","",""],["","",""],["","",""]]
countmove = 0
win = 'false'
for y in range(0,(len(grid))):
print(grid[y])
symbol = start_player()
while countmove != 9 or win == 'false':
countmove = 0
row, column = getmove()
mainturn(row,column)
win = check_win(row,column, symbol)
答案 0 :(得分：0)
这是因为两件事。首先，您要在循环中重置AttributeError: module 'pkg_resources' has no attribute 'declare_namespace'
值，因此它始终为零并进入无限循环。其次，在检查是否为胜利之前，您正在更改count_move，symbol例程正在检查下一个符号而不是播放器的当前符号。这是工作代码：
check_win子程序change_symbol在这里：
while countmove != 9 or win == 'false':
row, column = getmove()
mainturn(row,column)
win = check_win(row,column, symbol)
symbol = change_symbol(symbol)
作为良好编码实践的一部分，避免在子程序中使用全局变量，这只会加剧混乱。

我尽力评论为什么我做了事以及为什么要删除东西。我希望这个例子可以帮助你了解为什么在使用python时使用类不能更好。我添加了一些其他功能，我认为可以帮助您继续学习编程
