# 3.Constructs a JSON dictionary containing the image URL with the key "image_url."

# 1.It sets the server variable to either a local or a web server URL based on the current execution context.
# If running locally, it's using "http://127.0.0.1:5000" as the server URL. If running from the web, it uses 'https://flask.nighthawkcodingsociety.com'.
# 2.It constructs the url by appending "/api/cityimage" to the server URL. This URL represents the endpoint of the Flask API.
# 3.It initializes an empty list called responses. This list is likely intended to store responses received from making HTTP requests to the url.
# The purpose of this list may become clearer in the rest of the code or in subsequent parts of the script.
WHat the code does
The provided code is a partial implementation of a Flask-based RESTful API for retrieving city images based on city names. It defines a Flask Blueprint with a URL prefix of /api/cityimage and uses Flask-RESTful to create an API (when put in postman it gives data the user will see). The incomplete CityImageAPI class is intended to handle API requests, and it contains an inner class _Read to respond to GET requests by fetching city image URLs using a function from the cityimagesmodel module. The code also sets up a server URL and prepares to make requests to the API, either running locally or remotely. However, the code lacks the full implementation of how the API should respond to requests, and the methods within the CityImageAPI class need to be defined for the API to work as intended.
