编写五子棋的完整python代码_python实现五子棋程序

好的，以下是五子棋的完整Python代码：

import numpy as np

# 定义棋盘大小
BOARD_SIZE = 15

# 定义棋子类型
EMPTY = 0
BLACK = 1
WHITE = 2

class Board:
    def __init__(self):
        self.board = np.zeros((BOARD_SIZE, BOARD_SIZE), dtype=np.int32)
        self.current_player = BLACK

    def get(self, x, y):
        return self.board[x][y]

    def put(self, x, y):
        self.board[x][y] = self.current_player

    def switch_player(self):
        self.current_player = WHITE if self.current_player == BLACK else BLACK

    def is_valid_move(self, x, y):
        if x < 0 or x >= BOARD_SIZE or y < 0 or y >= BOARD_SIZE:
            return False
        if self.board[x][y] != EMPTY:
            return False
        return True

    def is_game_over(self):
        # 判断横向是否有五子相连
        for i in range(BOARD_SIZE):
            for j in range(BOARD_SIZE - 4):
                if self.board[i][j] == self.board[i][j+1] == self.board[i][j+2] == self.board[i][j+3] == self.board[i][j+4] and self.board[i][j] != EMPTY:
                    return True

        # 判断竖向是否有五子相连
        for i in range(BOARD_SIZE - 4):
            for j in range(BOARD_SIZE):
                if self.board[i][j] == self.board[i+1][j] == self.board[i+2][j] == self.board[i+3][j] == self.board[i+4][j] and self.board[i][j] != EMPTY:
                    return True

        # 判断左上到右下是否有五子相连
        for i in range(BOARD_SIZE - 4):
            for j in range(BOARD_SIZE - 4):
                if self.board[i][j] == self.board[i+1][j+1] == self.board[i+2][j+2] == self.board[i+3][j+3] == self.board[i+4][j+4] and self.board[i][j] != EMPTY:
                    return True

        # 判断左下到右上是否有五子相连
        for i in range(4, BOARD_SIZE):
            for j in range(BOARD_SIZE - 4):
                if self.board[i][j] == self.board[i-1][j+1] == self.board[i-2][j+2] == self.board[i-3][j+3] == self.board[i-4][j+4] and self.board[i][j] != EMPTY:
                    return True

        return False

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

board = Board()

while True:
    print(board)
    if board.current_player == BLACK:
        print('黑方落子：')
    else:
        print('白方落子：')
    x = int(input('请输入x坐标：'))
    y = int(input('请输入y坐标：'))
    if board.is_valid_move(x, y):
        board.put(x, y)
        if board.is_game_over():
            print(board)
            print('游戏结束！')
            break
        board.switch_player()
    else:
        print('无效的落子！')

这个代码实现了一个文本版的五子棋游戏，可以在命令行中运行。玩家先输入x坐标，然后输入y坐标，程序会检测这个落子是否有效，并将棋子放在棋盘上。当有一方获胜时，程序会打印出游戏结束的消息。
