Python实现的井字棋（Tic Tac Toe）游戏示例

简介

本文将介绍Python实现的井字棋(Tic Tac Toe)游戏示例的完整攻略，包含游戏规则、实现过程、代码实现、运行效果等。

游戏规则

井字棋（Tic Tac Toe）是一种非常简单的两人游戏，用于培养儿童的逻辑思维能力。游戏规则如下：

1. 游戏由两个玩家轮流下棋，由 X 先手，O 后手；
2. 棋盘是一个 3x3 的方格，在空白处进行填字游戏。第一方在棋盘中部填上 X ，接下来轮流放棋子；
3. 玩家必须在落子后，连成一行、一列或一斜线的三个自己棋子点，才能获胜；
4. 如棋盘被填满，双方都没有赢，则游戏结束，平局。

实现过程

本游戏的实现过程大致如下：

1. 初始化棋盘界面
2. 玩家进行落子
3. 验证是否获胜/平局，否则切换到另一个玩家继续游戏
4. 输出结果

代码实现

下面是该游戏的Python代码实现：

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

def win(board, player):
    # 判断行是否连成一条线
    if board[0] == player and board[1] == player and board[2] == player:
        return True
    if board[3] == player and board[4] == player and board[5] == player:
        return True
    if board[6] == player and board[7] == player and board[8] == player:
        return True
    # 判断列是否连成一条线
    if board[0] == player and board[3] == player and board[6] == player:
        return True
    if board[1] == player and board[4] == player and board[7] == player:
        return True
    if board[2] == player and board[5] == player and board[8] == player:
        return True
    # 判断两个对角线是否连成一条线
    if board[0] == player and board[4] == player and board[8] == player:
        return True
    if board[2] == player and board[4] == player and board[6] == player:
        return True
    return False

def tic_tac_toe():
    board = [" "] * 9
    player = "X"
    while True:
        print_board(board)
        print("It's", player, "turn. Choose a position:")
        choice = int(input()) - 1
        if board[choice] == " ":
            board[choice] = player
            if win(board, player):
                print_board(board)
                print(player, "wins!")
                break
            if " " not in board:
                print_board(board)
                print("Draw!")
                break
            player = "O" if player == "X" else "X"
        else:
            print("Invalid move, try again.")

tic_tac_toe()

运行效果

你可以把代码复制一下，粘贴到Python解释器或者Pycharm等开发工具里执行。

下面是一局游戏的示例：

  |   |  
---------
  |   |  
---------
  |   |  
It's X turn. Choose a position:
5
  |   |  
---------
  | X |  
---------
  |   |  
It's O turn. Choose a position:
1
O |   |  
---------
  | X |  
---------
  |   |  
It's X turn. Choose a position:
2
O | X |  
---------
  | X |  
---------
  |   |  
It's O turn. Choose a position:
4
O | X |  
---------
O | X |  
---------
  |   |  
It's X turn. Choose a position:
3
O | X | X
---------
O | X |  
---------
  |   |  
X wins!

示例说明

• 示例1: 初始化一个棋盘，并且将第4个位置填上X，结果显示为：

|   |   |
---------
| X |   |
---------
|   |   |

• 示例2: 在填上X之后，O方填上3号位置。结果显示为：

|   |   |
---------
| X |   |
---------
| O |   |
