Python calculator with tkinter.

import tkinter
from tkinter import *

root = Tk()

numbers = Entry(root, width = 2)
number2 = Entry(root, width = 2)
key_plus = Button(text = "+")
key_minus = Button(text = "-")
key_multiply = Button(text = "*")
key_divon = Button(text = ":")
Claculete = Button(text = "calculte")
output = Label(width = 10)




def plusnumes():

Get_number1 = numbers.get()
Get_number2 = number2.get()
dm =(str(Get_number2))
dm1 =(str(Get_number2))
dm2 = (int(Get_number2))
dm3 =(int(Get_number2))
result = dm2 + dm3
z1 = (str(result))
output['text'] = (z1)




#algoritam
key_plus.bind('<Button-1>',plusnumes)
key_minus.bind('<Button-1>',)
key_multiply.bind('<Button-1>',)
key_divon.bind('<Button-1>',)






#visualzite
numbers.pack(),number2.pack()
Claculete.pack()
output.pack()
key_plus.pack()
key_minus.pack()
key_multiply.pack()
key_divon.pack()
root.mainloop()

The program starts normally but when I try to use the function plusnumes() outputs this error

Exception in Tkinter callback
Traceback (most recent call last):
