Tkinter遺忘在另一個功能內製作的小工具

Question

我想知道如何遺忘一個小工具而不是另一個功能？ 我的代碼很安靜。

def page2(cur1): 
    label2 = Label(root, text="How much would you like to convert?") 
    entry1 = Entry(root) 
    buttonSubmit = Button(root, text="Submit", command=lambda: get_entry(entry1, cur1)) 

    label2.grid(row=1, columnspan=5) 
    entry1.grid(row=2, sticky="w") 
    buttonSubmit.grid(row=2, column=1) 

我希望能夠忘記從另一個功能這些小部件，像這樣：提前

def forget(): 
    label2.grid_forget() 
    entry1.grid_forget() 

感謝。

如果你發現自己需要這麼多，你應該re-structure your program using classes。

您可以將窗口小部件的創建移動到全局範圍，並在需要時將其忽略。

#create your widgets in global scope so you can reach them in any function 
label2 = Label(root, text="How much would you like to convert?") 
entry1 = Entry(root) 

def page2(cur1): 
    buttonSubmit = Button(root, text="Submit", command=lambda: get_entry(entry1, cur1)) 

    label2.grid(row=1, columnspan=5) 
    entry1.grid(row=2, sticky="w") 
    buttonSubmit.grid(row=2, column=1) 

def forget(): 
    label2.grid_forget() 
    entry1.grid_forget()
