Create a CLI application in Python that interacts with the DuckDuckGo Search API to fetch relevant information based on user-provided parameters. The application should output the results to the terminal and write them to a file for future reference.
- Search Functionality:
- Accept a search query as a command-line argument.
- Use the DuckDuckGo Search API to fetch relevant data for the provided query.
- Output to Terminal:
- Display the search results in the terminal in a readable format.
- Write to File:
- Allow the user to specify a filename to write the search results to a text file.
- If no filename is provided, use a default filename (e.g., duckSearch_results.txt).
- User-Friendly CLI Interface:
- Implement a user-friendly CLI interface with clear instructions.
- Provide help messages and usage instructions.
- Error Handling:
- Implement error handling to manage API request failures, invalid input, or other potential issues gracefully.
- Display meaningful error messages to the user.
- Code Organization:
- Organize the code into modular functions and classes for readability and maintainability.
- Use a virtual environment to manage dependencies.
- Documentation:
- Include inline comments for important code segments.
- Write a README file explaining how to set up the project, run the application, and any other relevant information.
- Dependencies:
- requests: Use the requests library to make HTTP requests to the DuckDuckGo Search API.
- Respect the DuckDuckGo API usage policies and guidelines.
- Provide clear instructions in the README on how to obtain an API key if needed.
