用Python的tkinter库帮我写一个五子棋游戏

好的，下面是一个简单的五子棋游戏代码，你可以根据自己的需求进行修改。

import tkinter as tk

# 定义棋盘大小和棋子大小
BOARD_SIZE = 500
PIECE_SIZE = 20

class Board:
    def __init__(self):
        self.board = [[0 for _ in range(15)] for _ in range(15)]
        self.current_player = 1

    def play(self, x, y):
        if self.board[x][y] == 0:
            self.board[x][y] = self.current_player
            self.current_player = 3 - self.current_player
            return True
        else:
            return False

    def get_board(self):
        return self.board

class Game:
    def __init__(self):
        self.board = Board()
        self.root = tk.Tk()
        self.canvas = tk.Canvas(self.root, width=BOARD_SIZE, height=BOARD_SIZE)
        self.canvas.pack()
        self.draw_board()
        self.canvas.bind("<Button-1>", self.play)

    def draw_board(self):
        # 画棋盘
        for i in range(15):
            self.canvas.create_line(i * PIECE_SIZE, 0, i * PIECE_SIZE, BOARD_SIZE)
            self.canvas.create_line(0, i * PIECE_SIZE, BOARD_SIZE, i * PIECE_SIZE)

    def draw_piece(self, x, y):
        # 画棋子
        if self.board.current_player == 1:
            color = "black"
        else:
            color = "white"
        self.canvas.create_oval(x * PIECE_SIZE - PIECE_SIZE // 2,
                                y * PIECE_SIZE - PIECE_SIZE // 2,
                                x * PIECE_SIZE + PIECE_SIZE // 2,
                                y * PIECE_SIZE + PIECE_SIZE // 2,
                                fill=color, outline=color)

    def play(self, event):
        # 下棋
        x = round(event.x / PIECE_SIZE)
        y = round(event.y / PIECE_SIZE)
        if self.board.play(x, y):
            self.draw_piece(x, y)
            self.check_win()

    def check_win(self):
        # 判断胜负
        board = self.board.get_board()
        for i in range(15):
            for j in range(15):
                if board[i][j] != 0:
                    if i <= 10 and board[i][j] == board[i + 1][j] == board[i + 2][j] == board[i + 3][j] == board[i + 4][j]:
                        self.game_over(board[i][j])
                    if j <= 10 and board[i][j] == board[i][j + 1] == board[i][j + 2] == board[i][j + 3] == board[i][j + 4]:
                        self.game_over(board[i][j])
                    if i <= 10 and j <= 10 and board[i][j] == board[i + 1][j + 1] == board[i + 2][j + 2] == board[i + 3][j + 3] == board[i + 4][j + 4]:
                        self.game_over(board[i][j])
                    if i <= 10 and j >= 4 and board[i][j] == board[i + 1][j - 1] == board[i + 2][j - 2] == board[i + 3][j - 3] == board[i + 4][j - 4]:
                        self.game_over(board[i][j])

    def game_over(self, player):
        # 游戏结束
        if player == 1:
            color = "black"
        else:
            color = "white"
        self.canvas.create_text(BOARD_SIZE // 2, BOARD_SIZE // 2, text=color + " wins!", font=("Helvetica", 32))
        self.canvas.unbind("<Button-1>")

    def run(self):
        self.root.mainloop()

if __name__ == "__main__":
    game = Game()
    game.run()

运行这段代码，会弹出一个窗口，你可以在窗口中下五子棋。
