arrakis-schema

Create a Python-based weather forecasting mini-app that integrates with the Arrakis API using the 'arrakis-schema' package. Your app should allow users to input their location and retrieve detailed weather forecasts. Here are the steps and features you need to implement:

1. **Setup**: Install necessary packages including 'arrakis-schema', 'requests', and any other dependencies required for handling JSON data and making HTTP requests.
2. **Schema Utilization**: Use 'arrakis-schema' to validate and structure incoming and outgoing data from the Arrakis API. Ensure that your app strictly adheres to the schemas provided by 'arrakis-schema' for both request and response formats.
3. **User Interface**: Develop a simple command-line interface (CLI) where users can enter their city name or zip code to fetch weather information.
4. **Data Fetching**: Implement a function that takes user input, constructs a proper API request according to the schema, sends it to the Arrakis API, and retrieves the forecast data.
5. **Data Parsing & Validation**: Parse the received JSON data, ensuring it conforms to the 'arrakis-schema' specifications. Handle exceptions gracefully if the data doesn't match expected formats.
6. **Output Display**: Display the parsed weather data in an easily readable format. Include key details such as temperature, humidity, wind speed, and a summary of the weather conditions.
7. **Error Handling**: Implement robust error handling to manage issues like invalid user inputs, network errors, and incorrect responses from the API.
8. **Testing**: Write unit tests to ensure each component works as expected, especially focusing on how well the app handles various edge cases and unexpected inputs.
9. **Documentation**: Provide clear documentation on how to install and run the app, along with examples of valid inputs and expected outputs.

This project will showcase your ability to work with APIs, handle data validation through schemas, and create a functional CLI application.
