python五子棋代码

由于五子棋是一种游戏，属于交互式应用程序，需要图形界面，因此需要使用一些图形库。以下是一个使用 Tkinter 模块实现五子棋的 Python 代码示例：

import tkinter as tk

class Chessboard(tk.Canvas):
    def __init__(self, master=None, **kwargs):
        super().__init__(master, **kwargs)
        self.master = master
        self.init_chessboard()
        self.draw_chessboard()
        self.bind_events()

    def init_chessboard(self):
        self.n = 15  # 棋盘大小
        self.step = 30  # 棋盘格子大小
        self.stone_r = self.step // 2 - 2  # 棋子半径
        self.board = [[0] * self.n for _ in range(self.n)]  # 初始化棋盘状态
        self.color = 1  # 当前下棋方，0 表示黑方，1 表示白方
        self.game_over = False  # 游戏是否结束
        self.winner = None  # 获胜方

    def draw_chessboard(self):
        for i in range(self.n):
            self.create_line(self.step // 2, self.step // 2 + i * self.step,
                             self.step // 2 + (self.n - 1) * self.step, self.step // 2 + i * self.step)
            self.create_line(self.step // 2 + i * self.step, self.step // 2,
                             self.step // 2 + i * self.step, self.step // 2 + (self.n - 1) * self.step)

    def bind_events(self):
        self.bind("", self.place_stone)

    def place_stone(self, event):
        if self.game_over:  # 如果游戏已经结束，无法再下棋
            return
        x = round((event.x - self.step / 2) / self.step)
        y = round((event.y - self.step / 2) / self.step)
        if x < 0 or x >= self.n or y < 0 or y >= self.n:
            return
        if self.board[y][x] != 0:  # 如果该位置已经有棋子，无法再下棋
            return
        self.board[y][x] = self.color
        if self.check_win(x, y, self.color):  # 如果当前下棋方获胜，游戏结束
            self.game_over = True
            self.winner = self.color
        self.color = 1 - self.color  # 下一步改变下棋方
        self.draw_stone(x, y, self.color)

    def draw_stone(self, x, y, color):
        if color == 0:
            fill_color = "black"
        else:
            fill_color = "white"
        self.create_oval(x * self.step + self.step // 2 - self.stone_r,
                         y * self.step + self.step // 2 - self.stone_r,
                         x * self.step + self.step // 2 + self.stone_r,
                         y * self.step + self.step // 2 + self.stone_r,
                         fill=fill_color, outline="black", width=1)

    def check_win(self, x, y, color):
        directions = [(1, 0), (0, 1), (1, 1), (1, -1)]
        for dx, dy in directions:
            cnt = 1
            for step in (1, -1):
                nx, ny = x + step * dx, y + step * dy
                while 0 <= nx < self.n and 0 <= ny < self.n and self.board[ny][nx] == color:
                    cnt += 1
                    nx, ny = nx + step * dx, ny + step * dy
            if cnt >= 5:
                return True
        return False

class App(tk.Tk):
    def __init__(self):
        super().__init__()
        self.geometry("500x500")
        self.title("五子棋")
        self.chessboard = Chessboard(self, width=450, height=450)
        self.chessboard.pack(side="top", fill="both", expand=True)

if __name__ == "__main__":
    app = App()
    app.mainloop()

这是一个基本的五子棋交互式应用程序，你可以在棋盘上单击鼠标下棋，程序会自动检查是否有一方获胜或者平局。
