-# Python-Calculator
-Calculator i made in python with tkinter
+A very basic Calculator implemented in Python Programming Language using Tkinter Module.
+
+Operations Available = 1. Addition 2. Substraction 3. Division 4. Multiplication and many more.
+
+Advantages = 1. Bigger Buttons 2. Compact and Fast
+
+------------------------------------BASICS------------------------------------------------ 
+Python = is a Dynamically Typed, Object Oriented Programming Language
+Tkinter = Inbuilt Python module --> to create simple GUI apps. 
+        = Standard Python interface to Tk GUI toolkit.
+
+Tk = is the toolkit
+
+mainloop() = Most important function while working with Tkinter.
+           = You must call mainloop only one time. = It is an infinite loop.
+
+-----------------------------BASIC Code for Tkinter---------------------------------- from tkinter import *
+
+root = Tk()                 # 'root' is object of 'Tk' class 
+                            # creates a basic gui 
+                            # basic default compoments present in GUI 
+                            # A base is created -> for GUI Development 
+                            # we can create button, menu bar,etc on this base
+
+root.mainloop() # event loop -> called only once
