The given Python code snippet is written for a Flask web application. Here's what the code does:

1. It defines a route in a Flask application using the @app.route decorator. Specifically, it sets up an endpoint at the URL /routes that only accepts HTTP GET requests (methods=["GET"]).

2. It defines a function named show_routes() that will be executed when a GET request is made to the /routes endpoint.

3. Inside the function:

   • It accesses Flask's url_map attribute, which contains all the URL routing rules available in the application.
   • It iterates over these rules using app.url_map.iter_rules().
   • For each rule, it converts it to a string representation using str(rule).

4. Finally, it returns a JSON response containing a list of all available URL routes (their string representations) defined in the Flask application.

Purpose of this code:
This endpoint allows you to list and inspect all the routes registered in the Flask application. It's useful for debugging or seeing a quick overview of all endpoints in the project.
