我正在尝试使用grid_forget删除小部件，但无法正常工作

Question

我正在尝试使用grid_forget删除我的小部件，我以前在代码中使用过它并且工作正常，但是在这一部分中它不起作用

from tkinter import*
def hfmenureturn():
    hotfood.grid_forget()
def hotfood():
    hf.grid_forget()
    hotfoodhome = Button(order, text = 'Home', bg = 'white', fg = 'black', 
    font = 'arial 20 bold', command = hfmenureturn)
    hotfoodhome.grid(row = 0, column = 0)
order = Tk()
hf = Button (order, text = 'HOT FOOD', bg = 'red2', fg = 'black', font = 
'arial 15', width = 43, height = 7, command = hotfood)
hf.grid(row = 1, column = 0, sticky = W)

order.mainloop()

弹出的错误消息是AttributeError：“函数”对象没有属性“ grid_forget”
