To handle exceptions gracefully when the input file is missing or corrupted, I would use Python's try-except block. First, I would attempt to open and read the file within a try block. If the file is missing, a FileNotFoundError would be raised, and I would catch this in an except block, providing a user-friendly message indicating the file is not found and suggesting checking the file path. For a corrupted file, I would catch a more general exception, such as IOError, and inform the user that the file might be corrupted or unreadable. Additionally, I would log these errors for further analysis and ensure the script can continue running or exit gracefully without crashing. This approach helps in maintaining the robustness and user-friendliness of the application.
