python - 当我选择子菜单时，我试图隐藏我的主菜单屏幕小部件

Question

现在的问题是我留下了一个空白屏幕，而我的其他小部件没有显示

def hotfood():
    shclogo.grid_forget()
    maintitle1.grid_forget()
    maintitle2.grid_forget()
    hf.grid_forget()
    cf.grid_forget()
    frzn.grid_forget()
    drnks.grid_forget()
    snks.grid_forget()
    crt.grid_forget()
    hotfoodhome = Button(hotfood, text = 'Home', bg = 'white', fg = 
    'black', font = 'arial 20 bold')
    hotfoodhome.grid(row = 0, column = 0, sticky = EW)
    hotfoodtitle = Label (hotfood, text = 'HOT FOOD', bg = 'white', fg = 
    'black', font = 'arial 48 bold')
    hotfoodtitle.grid(row = 0, column = 1, sticky = EW)
