We can think of Blueprint as a module too. With the above background given on Flask Blueprint, we can move ahead and design our first Blueprint.
A set of operations are recorded and can be subsequently replayed after registering a blueprint. 
Increases the reusability of code by registering the same Blueprint multiple times. Easy organization of large scale applications. Some of the benefits of Flask Blueprints are as follows: from flask import Flaskįlask Blueprint lets us keep related features together and helps in better development practices. The instance of the class Flask is the Flask Application, which is the instance of WSGI application.
