Question

在我的井字游戏中，经过4个回合，它宣布X（第一个玩家）为获胜者，即使不是。我不知道我错过了什么，当只检查列但现在却没有行时它正在工作。当我用字母调用该函数时，我感到有问题，但我不确定。

moves = [["1", "2", "3"],
         ["1", "2", "3"],
         ["1", "2", "3"]]

def win(letter):
  if(moves[0][0] == letter and
     moves[1][0] == letter and
     moves[2][0] == letter):
    print("~~~ " + letter + " WON!!! CONGRATS!!!! ~~~")
    quit()
  elif(moves[0][1] == letter and
       moves[1][1] == letter and
       moves[2][1] == letter):
    print("~~~ " + letter + " WON!!! CONGRATS!!!! ~~~")
    quit()
  elif(moves[0][2] == letter and
       moves[1][2] == letter and
       moves[2][2] == letter ):
    print("~~~ " + letter + " WON!!! CONGRATS!!!! ~~~")
    quit()
  elif(moves[0][0] == letter and
       moves[0][1] == letter and
       moves[0][2]):
    print("~~~ " + letter + " WON!!! CONGRATS!!!! ~~~")
    quit()
  elif(moves[1][0] == letter and
       moves[1][1] == letter and
       moves[1][2]):
    print("~~~ " + letter + " WON!!! CONGRATS!!!! ~~~")
    quit()
  elif(moves[2][0] == letter and
       moves[2][1] == letter and
       moves[2][2]):
    print("~~~ " + letter + " WON!!! CONGRATS!!!! ~~~")
    quit()
def playerInput():
  player1 = input("Where do you want to place your X, player 1? (row number, space, number)")
  moves[int(player1[0]) - 1][int(player1[2]) - 1] = "X"
  player2 = input("Where do you want to place your O, player 2? (row number, space, number)")
  moves[int(player2[0]) - 1][int(player2[2]) - 1] = "O"
  boardDraw()
def boardDraw():
  print("1| "+moves[0][0]+" | "+moves[0][1]+" | "+moves[0][2]+" |")
  print(" |---+---+---|")
  print("2| "+moves[1][0]+" | "+moves[1][1]+" | "+moves[1][2]+" |")
  print(" |---+---+---|")
  print("3| "+moves[2][0]+" | "+moves[2][1]+" | "+moves[2][2]+" |")
  win("X")
  win("O")
  playerInput()

print("OK SO....\nPlayer 1 is X\nPlayer 2 is O\nGOOOOO!!")

boardDraw()

您显然错过了2个获胜案例：

moves[0][0] == moves[1][1] == moves[2][2]

和：

moves[0][2] == moves[1][1] == moves[2][0]

我宁愿将您的获奖检测功能重写为：

def win(letter) :
    for i in range(3) :  # rows
        if set(moves[i]) == set([letter]) :
            print( 'WIN' )
            quit()
    for x in zip(moves[0], moves[1], moves[2]) :  # columns
        if set(x) == set([letter]) :
            print( 'WIN' )
            quit()

    # you have completely missed the part below...
    if set(moves[i][i] for i in range(3)) == set([letter]) : # one diagonal
        print( 'WIN' )
        quit()
    if set(moves[i][3-i] for i in range(3)) == set([letter]) : # another diagonal
        print( 'WIN' )
        quit()

或更紧凑：

def win(letter) :
    possible_wins = [ set(moves[i]) for i in rage(3) ] +  # rows
        [ set(x) for x in zip(moves[0], moves[1], moves[2]) ] +  # columns
        [ set(moves[i][i] for i in range(3)) ] +  # diagonal
        [ set(moves[i][3-i] for i in range(3)) ]  # another diagonal
    if any( p == set([letter]) for p in possible_wins ) :
        print( 'WIN' )
        quit()

Answer 2

我假设您的问题的一部分与以下事实有关：在您的某些if线索中，您检查前两个平方或等于letter，而不检查第三个平方。除了None或0之类的内容外，Python中的大多数对象都将被评估为True。因此，如果您的数组或字符中有一个非零数字，它将被评估为True。这导致程序认为只有两件事组成一行时，玩家才赢了。

此外，您还有六个特定的获胜条件，而且肯定比您在井字游戏中获胜的条件还要多。我建议采用一种更合乎逻辑（且更具可读性）的方式将获胜方案整合在一起。例如，您可以在一个循环中检查所有水平和垂直获胜条件：

for i in range(3):
    if ((moves[i][0] == moves[i][1] == moves[i][2] == letter) or
         (moves[0][i] == moves[1][i] == moves[2][i] == letter):
        # do win-condition stuff here

最后，我建议您检查无效举动，因为您当前的代码只会让用户覆盖现有举动。
