隱藏所有這些網格，以便我可以製作另一個「頁面」

from tkinter import * 

rGui = Tk() 
rGui.title("Recipe's") 
rGui.geometry("400x300") 
rGui.resizable(0,0) 

rNameLabel = Label(rGui, text="What is your Recipe called?").grid(row=1, column=1) 
rEnt = Entry(rGui) 
rEnt.grid(row=1, column=2) 


def RecipeName(): 
    f = open(rEnt.get()+'.txt','a') 
    f.write("Recipe name: "+str(rEnt.get())+"\n") 
    f.close() 
rConButton = Button(rGui, text="Confirm", command=RecipeName).grid(row=1, column=3)

您好，這裏的代碼打開一個帶按鈕的GUI。現在，一旦用戶輸入他們的食譜名稱，我希望它清除屏幕，以便我可以添加更多的按鈕。現在我不知道如何讓grid_forget工作，所以如果有人可以編輯代碼以便它忘記它，所以我可以在下次看到它，我會很感激。隱藏所有這些網格，以便我可以製作另一個「頁面」

這是你如何能使用grid幾何管理程序中的頁面中的一個例子：

import tkinter 

class Application(tkinter.Frame): 

    @classmethod 
    def main(cls): 
     tkinter.NoDefaultRoot() 
     root = tkinter.Tk() 
     root.title('Recipes') 
     root.geometry('400x300') 
     root.resizable(False, False) 
     app = cls(root) 
     app.grid() 
     root.mainloop() 

    def __init__(self, master): 
     super().__init__(master) 
     self.create_first_screen() 
     self.first_screen.grid_remove() 
     self.create_second_screen() 
     self.second_screen.grid_remove() 
     self.first_screen.grid() 

    def create_first_screen(self): 
     self.first_screen = s1 = tkinter.Frame(self) 
     self.first_screen.grid(row=0, column=0) 
     # Create widgets. 
     s1.name_label = tkinter.Label(s1, text='What is your recipe called?') 
     s1.name_entry = tkinter.Entry(s1) 
     s1.con_button = tkinter.Button(s1, text='Confirm', 
             command=self.name_recipe) 
     # Grid each widget. 
     s1.name_label.grid(row=0, column=0) 
     s1.name_entry.grid(row=0, column=1) 
     s1.con_button.grid(row=0, column=2) 

    def create_second_screen(self): 
     self.second_screen = s2 = tkinter.Frame(self) 
     self.second_screen.grid(row=0, column=0) 
     # Create widgets. 
     s2.name_label = tkinter.Label(s2, text='What is your name?') 
     s2.name_entry = tkinter.Entry(s2) 
     s2.con_button = tkinter.Button(s2, text='Confirm', 
             command=self.name_yourself) 
     # Grid each widget. 
     s2.name_label.grid(row=0, column=0) 
     s2.name_entry.grid(row=0, column=1) 
     s2.con_button.grid(row=0, column=2) 

    def name_recipe(self): 
     name = self.first_screen.name_entry.get() 
     with open(name + '.txt', 'w') as file: 
      print('Recipe name:', name, file=file) 
     self.first_screen.grid_remove() 
     self.second_screen.grid() 

    def name_yourself(self): 
     name = self.second_screen.name_entry.get() 
     with open(name + '.txt', 'w') as file: 
      print('Your name:', name, file=file) 
     self.second_screen.grid_remove() 
     self.first_screen.grid() 

if __name__ == '__main__': 
    Application.main()
