Question

这是我的代码的简单示例：

from tkinter import *
import random


class A:

    def __init__(self, master):
        n = random.randrange(1, 10, 1)
        self.frame_a = Frame(master)
        self.frame_a.pack()
        self.label_a = Label(self.frame_a, text=n)
        self.label_a.pack()

    def clean(self):
        self.frame_a.destroy()
        A(root)
        B(root)


class B:

    def __init__(self, master):
        self.frame_b = Frame(master)
        self.frame_b.pack()
        self.button_b = Button(self.frame_b, text='again', command=self.do_again)
        self.button_b.pack()

    def do_again(self):
        self.frame_b.destroy()
        hello.clean()


root = Tk()
hello = A(root)
world = B(root)
root.mainloop()

我要删除所有帧并标记并重新启动程序。但它没有正常工作。当我第一次使用按钮again时，它可以工作。但是，如果我再次单击按钮，则框架不会被破坏。

编辑：这是我的代码示例：

class GamePick:

    def __init__(self):
        #there are also some labels and frames but they relate to my problem

    def do_black_jack(self):
        global bj
        global bj_play
        ''' You pick Black Jack, open new window and close actual window'''
        bj = Toplevel(self.master)
        bj_play = BjGui(bj)
        bj['bg'] = 'springgreen4'
        bj.wm_geometry("1500x900")
        Choices.close(my)

class BlackJack:

   #There are some function for pick new card for player and dealer

    def check_limit(self):#
        if sum(player_cards_val) > 21:
            if 11 in player_cards_val:
                    player_cards_val.remove(11)
                    player_cards_val.append(1)
                    self.check_limit()
            else:
                    bj_play.show_result(res='Dealer win')
        elif sum(bot_cards_val) > 21:
            if 11 in bot_cards_val:
                    bot_cards_val.remove(11)
                    bot_cards_val.append(1)
                    self.check_sixteen()
            else:
                    bj_play.show_result(res='Player win')
        else:
            if sum(player_cards_val) > sum(bot_cards_val):
                    bj_play.show_result(res='Player win')
            else:
                    bj_play.show_result(res='Dealer win')



class BjGui:


    def __init__(self, master):
        self.master = master
        self.bot_frame = Frame(self.master, height=False, width=False, bg='springgreen4')
        bj.wm_geometry("1500x900")
        self.bot_frame.pack(side='top', pady=20)
        self.player_frame = Frame(self.master, height=False, width=False, bg='springgreen4')
        bj.wm_geometry("1500x900")
        self.player_frame.pack(side='bottom', pady=20)
        self.buttons_frame = Frame(self.master, bg='springgreen4')
        self.buttons_frame.pack(side=BOTTOM)
        # There are function for this class, they show players cards and bots cards from class Black Jack


    def show_result(self, res):#This function, create new label and button.
                               #  New label show result of the game, after I click button, it should will restart 
        self.info_label = Label(self.master, text=res, font=('aharoni', 60), bg='springgreen4', pady=35)
        self.info_label.pack()
        self.again_frame = Frame(self.master)
        self.again_frame.pack()
        self.again_bt = Button(self.again_frame, text='play again', font=('times', 12), command=self.do_again, bg='blue')
        self.again_bt.pack()

    def do_again(self):# This should delete all frames and clear list with cards and restart game, but it doesn't work
        self.info_label.destroy()
        self.again_frame.destroy()
        self.player_frame.destroy()
        self.bot_frame.destroy()
        self.buttons_frame.destroy()
        bot_cards_key.clear()
        bot_cards_val.clear()
        player_cards_key.clear()
        player_cards_val.clear()
        no_repeat.clear()
        BlackJack()
        BjGui(bj)

我想创建Black Jack游戏。 class BlackJack为玩家和经销商挑选新牌，比较这些牌的价值，并确定谁是赢家。 class BjGui显示玩家和经销商卡片，有一些按钮框架和标签。当游戏结束时，我使用函数check_limit，它会阻止谁是胜利者并且函数show_result使用结果和新按钮创建新标签。这个按钮应该能够重启游戏。

我不认为你想要你拥有的对象递归。您在当前正在使用的A内进行了新的B和A - 堆栈顶部。 hello和world仅引用堆栈的底部，而不是对象递归堆栈中的所有其他A和B。

另外，我不确定你为什么要两个不同的类或两个不同的帧。我将不得不理解你想要提出的关于如何使用不同的框架和类的建议。

from tkinter import *
import random


class A:
    def __init__(self):
        self.master = Tk()

        self.frame_a = None
        self.label_a = None  # not necessary, but common styling preference
        self.button_b = None  # not necessary, but common styling preference

        self.clean()
        self.master.mainloop()

    def clean(self):
        if self.frame_a is not None:
            self.frame_a.destroy()
        n = random.randrange(1, 10, 1)
        self.frame_a = Frame(self.master)
        self.frame_a.pack()
        self.label_a = Label(self.frame_a, text=n)
        self.label_a.pack()
        self.button_b = Button(self.frame_a, text='again', command=self.clean)
        self.button_b.pack()


hello = A()

Python tkinter，重启程序
