井字游戏的实现

井字游戏是一种非常经典的两人对弈游戏,又称为 "井字棋"。它不仅简单易学,而且能够培养孩子的逻辑思维能力。本文将介绍如何用 Python 实现井字游戏,让您了解游戏实现的基本原理。

游戏规则
  • 井字游戏是由一个 3x3 的方格组成的棋盘,其中一方使用圆圈(O),另一方使用叉号(X),轮流在棋盘上落子,先在行、列或对角线上连成三个相同标记的玩家即获胜。
  • 如果棋盘被填满,并且没有一方获胜,游戏就会以平局告终。
实现思路
  • 首先创建一个3x3的棋盘;
  • 然后实现落子功能,根据当前玩家在棋盘上落子;
  • 判断玩家是否获胜,获胜则游戏结束;
  • 每次玩家落子后,交换下一个玩家,直到棋盘被填满或有一方获胜。
代码实现
# 定义棋盘
board = [
    ['-','-','-'],
    ['-','-','-'],
    ['-','-','-']
]

# 定义当前玩家,默认为 X
current_player = 'X'

# 打印棋盘
def print_board(board):
    for row in board:
        print(" ".join(row))

# 判断是否获胜
def is_winner(board, player):
    # 检查行
    for row in board:
        if row.count(player) == 3:
            return True
    # 检查列
    for col in range(3):
        if board[0][col] == player and board[1][col] == player and board[2][col] == player:
            return True
    # 检查对角线
    if board[0][0] == player and board[1][1] == player and board[2][2] == player:
        return True
    if board[0][2] == player and board[1][1] == player and board[2][0] == player:
        return True
    return False

# 落子函数
def place_piece(board, player, row, col):
    if board[row][col] == '-':
        board[row][col] = player
        return True
    else:
        return False

# 交换玩家
def switch_player(current_player):
    if current_player == 'X':
        return 'O'
    else:
        return 'X'

# 清屏函数
def clear_screen():
    print("\n" * 50)

# 主函数
def main():
    print("Welcome to Tic Tac Toe!")

    while True:
        print_board(board)

        row = int(input(f"Player {current_player}, select a row (0, 1, 2): "))
        col = int(input(f"Player {current_player}, select a col (0, 1, 2): "))

        if place_piece(board, current_player, row, col):
            if is_winner(board, current_player):
                print_board(board)
                print(f"Player {current_player} wins!")
                break
            elif '-' not in board[0] and '-' not in board[1] and '-' not in board[2]:
                print_board(board)
                print("It's a tie!")
                break
            else:
                current_player = switch_player(current_player)
                clear_screen()
        else:
            print("That spot is already taken. Try again.")

if __name__ == "__main__":
    main()
