python - Python Tkinter 增量（默认值为零）

Question

我正在尝试使用 python tkinter 制作一个程序。每当我单击按钮时，我都想增加或减少输入框。它适用于我的代码。唯一的问题是每当我想刷新或按下另一个按钮以使增量回到零时？我怎样才能做到这一点？我试图删除输入框，但出现错误。谢谢

下面只是我的代码片段，因为它很长。谢谢

global number1, number2, number3, number4, number5, number6, number7, new_price
    new_price = []
    number1= IntVar()
    number2 = IntVar()
    number3 = IntVar()
    number4 = IntVar()
    number5 = IntVar()
    number6 = IntVar()
    number7 = IntVar()

self.entry2 = Entry(classic_milk, textvariable=number2, justify="center")
    self.entry2.place(relx=0.448, rely=0.738, width=25, height=15)
    self.entry2.configure(font="-family {Poppins} -size 10")
    self.entry2.configure(relief="flat")
    self.entry2.configure(bg="#dadada")
    #self.entry2.insert(0, textentry)

    self.entry3 = Entry(classic_milk, textvariable=number3, justify="center")
    self.entry3.place(relx=0.448, rely=0.775, width=25, height=15)
    self.entry3.configure(font="-family {Poppins} -size 10")
