python 五子棋

五子棋是一种古老的策略棋类游戏，目标是在棋盘上连成一条直线的五个棋子。在Python中实现五子棋可以使用各种方法，以下是一个简单的示例代码：

# 定义棋盘大小
board_size = 15

# 初始化棋盘
board = [[' ' for _ in range(board_size)] for _ in range(board_size)]

# 打印棋盘
def print_board(board):
    for row in board:
        print('|'.join(row))
        print('-' * (board_size * 2 - 1))

# 判断是否胜利
def is_winner(board, row, col, player):
    # 横向判断
    if col <= board_size - 5:
        if all(board[row][col+i] == player for i in range(5)):
            return True
    # 纵向判断
    if row <= board_size - 5:
        if all(board[row+i][col] == player for i in range(5)):
            return True
    # 斜向判断
    if row <= board_size - 5 and col <= board_size - 5:
        if all(board[row+i][col+i] == player for i in range(5)):
            return True
    if row <= board_size - 5 and col >= 4:
        if all(board[row+i][col-i] == player for i in range(5)):
            return True
    return False

# 下棋
def play(board):
    player = 'X'
    while True:
        print_board(board)
        print(f"轮到玩家{player}下棋")
        row = int(input("请输入行号："))
        col = int(input("请输入列号："))
        if board[row][col] == ' ':
            board[row][col] = player
            if is_winner(board, row, col, player):
                print(f"玩家{player}获胜！")
                break
            player = 'O' if player == 'X' else 'X'
        else:
            print("该位置已有棋子，请重新选择")

# 开始游戏
play(board)

这是一个简单的命令行版五子棋游戏，玩家通过输入行号和列号来下棋，游戏会判断是否胜利并打印棋盘。你可以根据自己的需求进行定制和扩展。
