python五子棋源代码

以下是一个简单的 Python 五子棋源代码示例：

import numpy as np

class Board:
    def __init__(self, size):
        self.size = size
        self.board = np.zeros((size, size), dtype=int)
        self.player = 1

    def move(self, x, y):
        if x >= self.size or y >= self.size or self.board[x][y] != 0:
            return False
        self.board[x][y] = self.player
        self.player = 3 - self.player
        return True

    def check_win(self):
        player = 3 - self.player
        for i in range(self.size):
            for j in range(self.size):
                if self.board[i][j] == player:
                    if self.check_line(i, j, 0, 1) or self.check_line(i, j, 1, 0) or self.check_line(i, j, 1, 1) or self.check_line(i, j, -1, 1):
                        return player
        return 0

    def check_line(self, x, y, dx, dy):
        count = 0
        player = self.board[x][y]
        while x >= 0 and x < self.size and y >= 0 and y < self.size and self.board[x][y] == player:
            count += 1
            x += dx
            y += dy
        return count >= 5

    def __str__(self):
        result = '  '
        for i in range(self.size):
            result += str(i) + ' '
        result += '\n'
        for i in range(self.size):
            result += str(i) + ' '
            for j in range(self.size):
                if self.board[i][j] == 0:
                    result += '. '
                elif self.board[i][j] == 1:
                    result += 'X '
                else:
                    result += 'O '
            result += '\n'
        return result

def main():
    board = Board(15)
    print(board)
    while True:
        x = int(input("X: "))
        y = int(input("Y: "))
        if board.move(x, y):
            print(board)
            winner = board.check_win()
            if winner != 0:
                print("Player %s wins!" % winner)
                break
        else:
            print("Invalid move.")

if __name__ == '__main__':
    main()

这个示例中，我们使用了 numpy 来创建并管理棋盘，其中 0 表示空白，1 表示黑子，2 表示白子。我们还实现了一个 check_win() 方法来检查是否有玩家获胜。在主函数中，我们使用 input() 函数来读取玩家的输入，并在每次落子后检查是否有玩家获胜。
