This project implements a simple Flask-based backend API for weather data. It allows users to retrieve weather information for specific cities, add new weather data, update existing weather data, and delete weather data for a city.

The project follows the following folder structure:

• app.py: The main Flask application file. It initializes the Flask app, registers routes, and starts the server.
• routes/weather_routes.py: Defines the routes for weather data operations.
• controllers/weather_controllers.py: Contains the controller functions for handling weather data operations.
• tests/weather_test.py: Contains test cases to verify the functionality of the API endpoints.

1. Start the server by running the app.py file.

2. Access the API endpoints using the following routes:

   • GET /weather-api/weather/<city>: Retrieve weather data for a specific city.
   • POST /weather-api/weather: Add new weather data for a city.
   • PUT /weather-api/weather/<city>: Update weather data for a specific city.
   • DELETE /weather-api/weather/<city>: Delete weather data for a specific city.

   Replace <city> with the name of the city you want to perform the operation on.

• Endpoint: GET /weather-api/weather/<city>
• Description: Retrieve weather data for a specific city.
• Response: JSON object containing the weather information for the city.

• Endpoint: POST /weather-api/weather
• Description: Add new weather data for a city.
• Request Body: JSON object containing the city, temperature, and weather information.
• Response: JSON object containing the success message and the added weather data.

• Endpoint: PUT /weather-api/weather/<city>
• Description: Update weather data for a specific city.
• Request Body: JSON object containing the updated temperature and/or weather information.
• Response: JSON object containing the updated weather data.

• Endpoint: DELETE /weather-api/weather/<city>
• Description: Delete weather data for a specific city.
• Response: JSON object confirming the deletion of the weather data.

The project includes test cases to verify the functionality of the API endpoints. The test cases are defined in the tests/weather_test.py file.

To run the tests, use the following command:

pytest tests/weather_test.py

Note : Make sure you have the pytest library installed.
