The application source code for lab 2 is located in hello.py
The request context keeps track of the request-level data during a request. Rather than passing the request object to each function, it's globally accessible through request and session.
A Request object called request containing the environment it received from the WSGI server is made for every request. The request data is global during the handling of the request.
A dictionary called session is used by the application to store values that are remembered between requests within a user session.
The application context keeps track of the application-level data during a request, including configurations. Rather than passing the application to each function, it's globally accessible through current_app and g.
The current_app function points to the application instance handling the current activity, it can be used to access data about the running application, including the configuration.
The g object can be used by the application for temporary storage while handling requests. The object is reset for each new request.
