Weather CLI

This is a command-line interface (CLI) application for retrieving weather information for a specified city using the OpenWeatherMap API.

Installation

1. Clone this repository to your local machine.
2. Install the required packages using pip:

pip install requests click

3. Obtain an API key from OpenWeatherMap and replace your_api_key_here with your actual API key in weather.py.

Usage

To use this CLI application, run the weather.py script in the terminal and enter the name of a city when prompted:

python weather.py

The CLI will retrieve weather information from the OpenWeatherMap API and display the current temperature and weather description for the specified city.

Enter city name: San Francisco
Temperature in San Francisco: 15 C
Weather description: clear sky

Dependencies

Update History

Version 1.1

In this updated code::

• Error Handling: The make_api_request function now raises an exception if the response status code is not 200. The get_weather function handles this exception and logs an error message.
• Input Validation: Input validation is not explicitly performed in this code snippet. However, the OpenWeatherMap API will respond with an appropriate error if an invalid city name is provided.
• API Key Handling: The API key is retrieved from an environment variable using os.getenv. Make sure to set the OPENWEATHERMAP_API_KEY environment variable with your actual API key.
• Unit Testing: While unit testing is not included in this code snippet, it is recommended to write unit tests for functions like make_api_request, parse_weather_data, and display_weather to verify their behavior under different scenarios.
• Modularity: The code has been organized into separate functions for making the API request, parsing the response, and displaying the weather information. This improves code readability, testability, and reusability.
• Logging: Logging has been incorporated using the logging module. The log messages are written to a file specified by LOG_FILE. The logging level is set to INFO, but you can adjust it as needed.

Remember to set the OPENWEATHERMAP_API_KEY environment variable with your actual API key before running the script.
