python五子棋人机对战

好的，下面是一个简单的Python五子棋人机对战程序：

import random

class Board:
    def __init__(self):
        self.board = [[' ' for i in range(15)] for j in range(15)]
        self.player = 'X'
        self.computer = 'O'

    def show(self):
        print(" ", end='')
        for i in range(15):
            print(" " + str(i + 1) + " ", end='')
        print("")
        for i in range(15):
            print(str(i + 1) + " ", end='')
            for j in range(15):
                print(self.board[i][j] + " |", end='')
            print("")
            print("  ---" * 15)

    def has_winner(self, player):

                    return True
        for i in range(11):

                    return True
        return False

    def get_winner(self):
        if self.has_winner(self.player):
            return self.player
        elif self.has_winner(self.computer):
            return self.computer
        else:
            return None

    def get_legal_moves(self):
        legal_moves = []
        for i in range(15):
            for j in range(15):
                if self.board[i][j] == ' ':
                    legal_moves.append((i, j))
        return legal_moves

    def player_move(self, row, col):
        if self.board[row][col] == ' ':
            self.board[row][col] = self.player
            return True
        else:
            return False

    def computer_move(self):
        legal_moves = self.get_legal_moves()
        row, col = random.choice(legal_moves)
        self.board[row][col] = self.computer

    def game_over(self):
        if self.get_winner() is not None:
            return True
        for i in range(15):
            for j in range(15):
                if self.board[i][j] == ' ':
                    return False
        return True


def main():
    board = Board()
    while not board.game_over():
        board.show()
        if board.player == 'X':
            while True:
                row = int(input("Enter row number: ")) - 1
                col = int(input("Enter column number: ")) - 1
                if board.player_move(row, col):

        board.player, board.computer = board.computer, board.player
    board.show()
    winner = board.get_winner()
    if winner is None:
        print("It's a tie!")

        print(winner + " wins!")


if __name__ == '__main__':
    main()

这个程序中，我们定义了一个`Board`类，它代表了五子棋棋盘。在类中，我们定义了一些方法来实现游戏逻辑：

- `show()`方法用于显示当前棋盘状态；
- `has_winner(player)`方法用于检查指定玩家是否获胜；
- `get_winner()`方法用于获取获胜方，如果没有获胜方则返回`None`；
- `get_legal_moves()`方法用于获取当前合法的落子位置；
- `player_move(row, col)`方法用于让玩家落子；
- `computer_move()`方法用于让电脑落子；
- `game_over()`方法用于检查游戏是否结束。

在`main()`函数中，我们创建一个`Board`对象，并在循环中交替让玩家和电脑落子，直到游戏结束。最后，我们打印出胜利者或者平局的结果。

你可以试着运行这个程序并和电脑对战，体验一下五子棋的乐趣。
