-# GUI-scientific-calculator-using-python
-it's a scientific calculator using python.It will consist a  graphical user interface using Tkinter  libraries in python.
+Hey Guys it's a python GUI (Made with Tkinter) Calculator project.
+
+To Create the Application:-
+        1) Importing the module – tkinter
+        2) Create the main window (container)
+        3) Add any number of widgets to the main window
+        4) Apply the event Trigger on the widgets.
+
+Let’s create a GUI based simple calculator using Python Tkinter module, which can perform basic arithmatic operations addition, subtraction, multiplication and division.
+
+Have a Look at my code (main.py)......
+
+Follow Me on :---
