: When writing custom decorators for report generation, it is best practice to use @functools.wraps to ensure the original function's name and docstring are preserved for debugging and documentation. Related Tools for Report Generation : When writing
: The decorated function executes when a user clicks a specific download button or link in the UI. Return Types :
: For temporary files or large data, the function can yield strings or bytestrings, allowing the app to clean up resources after the download completes.
: Using decorators allows core business logic (e.g., calculate_sales() ) to remain clean, while the decorator handles logging, execution timing, or formatting the output into a downloadable file.
