Python Tkinter program for the simple calculator

In this program, you will learn how to create a simple calculator using Tkinter in Python.

``````b1 = tk.Button(root, text="+", command=findsum).place(x=200, y=300)
b2 = tk.Button(root, text="-", command=findsub).place(x=250, y=300)
b2 = tk.Button(root, text="*", command=findmul).place(x=300, y=300)
b2 = tk.Button(root, text="/", command=finddiv).place(x=350, y=300)
``````

``````import tkinter as tk
