Routing helps organize by clearly linking URLs to specific functions, making the app easier to understand and maintain.

What does the @app.route decorator do in Flask?

A Handles database connections

B Starts the Flask server

C Imports Flask modules

D Links a URL path to a function

The @app.route decorator tells Flask which URL should trigger the decorated function.

What response does Flask give if no route matches a URL?

A 200 OK

B 404 Not Found

C 500 Internal Server Error

D 302 Redirect

Why is routing important in Flask?

A It connects URLs to code functions

B It manages user sessions

C It styles the web pages

D It stores data in a database

Routing connects web addresses to the functions that handle them.

Which of these is a valid Flask route definition?

A @app.route('/home')

B def route('/home'):

C route('/home') => function

D app.route('/home') = function

Flask uses the @app.route decorator to define routes.

What would happen if Flask had no routing system?

A It would automatically generate pages

B It would connect to databases

C It would not know how to respond to URLs

D It would style the website

Without routing, Flask can't match URLs to code, so it can't respond properly.

Explain in your own words why routing is the core of Flask.

Think about how a website knows what to show when you visit a link.

Describe how you would create a new route in a Flask app.

Remember the special symbol @ before route.
