MenubarCommand.py

import tkinter as tk

class playerSettings(tk.Frame):
    def __init__(self,parent=tk.Frame):
        tk.Frame.__init__(self,parent)

        self.parnt=parent
        self.parnt.title("Player Setting")

        self.p1name='Player 1'
        self.p2name='Player 2'
        self.p1symbol='x'
        self.p2symbol='o'

        # **********************************#
        self.p1NameLabel = tk.Label(parent, text='Player 1: Name ')
        self.p1NameLabel.grid(row=0, column=0)
        self.p1NameEntry = tk.Entry(parent)
        self.p1NameEntry.insert(0,self.p1name)
        self.p1NameEntry.bind('<FocusIn>', lambda event:self.p1NameEntry.delete(0,'end'))
        self.p1NameEntry.grid(row=0, column=1)


        apply=tk.Button(parent, text="Apply Settings", fg='white', bg='gray', command=self.saveStat)
        apply.grid(row=2, rowspan=1, columnspan=4)


    def saveStat(self):
        print('Settings Window Destroyed')
        self.p1name=self.p1NameEntry.get()
        print(self.p1name)
        self.parnt.destroy()

我想从已创建的另一个文件中的另一个类的实例更改一个文件中实例的属性值。当我在MenubarComman.py文件中更改默认播放器名称时，我想从MainTicTacToe.py类中访问更改的名称。我怎么能这样做？
我是Python的新手。

先谢谢。

你的问题源于2个Tk（）实例，以及草率编程，即有时你使用父，有时候self.parnt是一个坏习惯，所以一切都变成了self.top所以错误会弹出，如果这两个中的任何一个仍然存在..你还必须有一个方法来发出PlayerSetting（）完成时的信号。程序结构的方式，我所知道的唯一方法是使用递归检查“活着”。您也可以让PlayerSettings在完成时调用Game（）中的函数，这将打印该值。我已经清理了你的代码，它按照我的理解应该工作..请注意，这两个类在同一个文件中，以便于测试和发布。

import tkinter as tk

##import MenubarCommand as mbc

class Game():
    def __init__(self,parent):

        self.parnt=parent
        # self.parnt.geometry('500x300')
        self.parnt.title("Tic Tac Toe")
        # self.pack()

        menubar=tk.Menu(parent)
        # 'settings' menu
        settingsOption=tk.Menu(menubar, tearoff=0, bg="yellow")
        settingsOption.add_command(label='Player Settings', command=self.doit)
        settingsOption.add_command(label='Board Settins', command=self.doit)
        menubar.add_cascade(label='Setings', menu=settingsOption)

        # without using this method, menubar isn't shown in Frame
        self.parnt.config(menu=menubar)


    def doit(self):
        ## do not open more than one Tk() instance
        ##root=self.win()
        self.top=tk.Toplevel(self.parnt)
        self.set_it=PlayerSettings(self.top)
        self.get_variable()
        ##root.mainloop()


    def get_variable(self):
        """ check continuously if PlayerSettings has exited and
            if so, get the Entry's value
        """
        if self.set_it:
            self.parnt.after(1000,  self.get_variable)
        else:
            print("from Game", self.set_it.p1name)

    def win(self):
        return tk.Tk()


class PlayerSettings():
    def __init__(self, parent):
        self.top=parent

        self.p1name='Player 1'
        self.p2name='Player 2'
        self.p1symbol='x'
        self.p2symbol='o'

        # **********************************#
        self.p1NameLabel = tk.Label(self.top, text='Player 1: Name ', bg="lightblue")
        self.p1NameLabel.grid(row=0, column=0)
        self.p1NameEntry = tk.Entry(self.top)
        self.p1NameEntry.focus_set()
        self.p1NameEntry.insert(0,self.p1name)
        ##self.p1NameEntry.bind('<FocusIn>', lambda event:self.p1NameEntry.delete(0,'end'))
        self.p1NameEntry.grid(row=0, column=1, sticky="nsew")


        apply=tk.Button(self.top, text="Apply Settings", fg='white', bg='gray', command=self.saveStat)
        apply.grid(row=2, rowspan=1, columnspan=4)

    def saveStat(self):
        self.p1name=self.p1NameEntry.get()
        print(self.p1name)
        print('Settings Window Destroyed')
        self.top.destroy()

root=tk.Tk()
Game(root)
root.mainloop()

从tkinter python 3中稍后创建的另一个类的实例更新已创建的类实例的属性值
