如何在不退出程序的情况下退出tkinter中的窗口？

Question

我想第二个'Enter'按钮允许用户从这个窗口中退出。命令是什么？我相信self.quit会退出一切，但我用过的命令不起作用。

import tkinter as tk 

class Enter_Name_Window(tk.Toplevel): 
    '''A simple instruction window''' 
    def __init__(self, parent): 
     tk.Toplevel.__init__(self, parent) 
     self.text = tk.Label(self, width=40, height=2, text= "Please enter your name and class.") 
     self.text.pack(side="top", fill="both", expand=True) 

     enter_name = Entry(self) 
     enter_name.pack() 
     enter_name.focus_set() 


     def callback(): 
      self.display_name = tk.Label(self, width=40, height=2, text = "Now please enter your tutor group.") 
      self.display_name.pack(side="top", fill="both", expand=True) 
      tutor = Entry(self) 
      tutor.pack() 
      tutor.focus_set() 
      Enter_0.config(state="disabled") 

      Enter_0_2 = Button(self, text="Enter", width=10, command=Enter_Name_Window.quit) 
      Enter_0_2.pack() 

     Enter_0 = Button(self, text="Enter", width=10, command=callback) 
     Enter_0.pack()

有很多的错误与最值得注意的是开始：

command=Enter_Name_Window.quit 

应该从使用quit()方法，其不稳定的

command=self.destroy 

副歌，并通过类的实例self而不是新的类对象

Anywhere Anywhere e的修改后的代码：

class Enter_Name_Window(tk.Toplevel): 
    '''A simple instruction window''' 
    def __init__(self, parent): 
     tk.Toplevel.__init__(self, parent) 
     self.parent = parent 
     self.text = tk.Label(self.parent, width=40, height=2, text= "Please enter your name and class.") 
     self.text.pack(side="top", fill="both", expand=True) 

     enter_name = tk.Entry(self) 
     enter_name.pack() 
     enter_name.focus_set() 


     def callback(): 
      self.display_name = tk.Label(self.parent, width=40, height=2, text = "Now please enter your tutor group.") 
      self.display_name.pack(side="top", fill="both", expand=True) 
      tutor = tk.Entry(self.parent) 
      tutor.pack() 
      tutor.focus_set() 
      Enter_0.config(state="disabled") 

      Enter_0_2 = tk.Button(self.parent, text="Enter", width=10, command=self.destroy) 
      Enter_0_2.pack() 

     Enter_0 = tk.Button(self.parent, text="Enter", width=10, command=callback) 
     Enter_0.pack()
