In Flask, routing is how you connect URLs to functions in your application. This is handled using route decorators.
A route in Flask is defined with the @app.route() decorator. It tells Flask what URL should trigger a specific function (called a view function). When a user visits a certain URL, Flask runs the associated function and returns the result (usually HTML or JSON).

You can add variables to routes using <variable_name>:
