I am trying to make a tkinter program that calculates the land transfer tax. When I run this code, it gives me the following error when I try to calculate it:

Exception in Tkinter callback

Traceback (most recent call last):

  File "C:UsersAngelaAppDataLocalProgramsPythonPython37-    32libtkinter__init__.py", line 1705, in __call__

    return self.func(*args)

  File "C:/Users/Angela/PycharmProjects/Editor/Editor.py", line 16, in <lambda>

    ok = Button(master, text="Calculate tax", command= lambda: callback(master, entry_box)).grid(row=0, column=2)

  File "C:/Users/Angela/PycharmProjects/Editor/Editor.py", line 19, in callback

    price = entry_box.get()

AttributeError: 'NoneType' object has no attribute 'get'

Here is the code that I have:

master = Tk()



label = Label(master, text="Price of house: ").grid(row=0)

entry_box = Entry(master).grid(row=0, column=1)



ok = Button(master, text="Calculate tax", command= lambda: callback(master, entry_box)).grid(row=0, column=2)



def callback(master, entry_box):

    price = entry_box.get()

    price = int(price)

    tax_price = 275

    if price > 55000:

        tax_price += (250000 - 55000) * 0.1

    else:

        tax_price += 55000 * 0.05

    if price > 250000:

        tax_price += (368333 - 250000) * 0.15

    if price > 368333:

        tax_price += (400000 - 368333) * 0.15

    if price > 400000:

        tax_price += (2000000 - 400000) * 0.2

    if price > 2000000:

        tax_price += (price - 2000000) * 0.25

    show_tax_price = Label(master, text=tax_price).grid(row=0, column=3)







mainloop()

Can someone tell me what is wrong with my program?
