What is an app?
===============
==> the individual chunk/part/section of the website/Django project is called as a " Django app".
==> the structure of the app in Django is:
	assume app name ==> "foodMenu"
	foodMenu
		==> migrations
		__init__.py
		admin.py
		apps.py
		models.py	
		tests.py		
		views.py

Create the app:
	open command prompt ==> type a command: "$python manage.py startapp application-name"

Views.py:
=========
==> a python file
	can process user request

view ========> 1) take the request
		2) analyze the request
		3) provide the appropriate response.

How to write a view to our app:
