Handling the Ctrl-C signal in Python allows you to gracefully terminate a script or ignore the signal depending on your requirements. By using the KeyboardInterrupt exception or the signal module, you can control how your script responds to the user pressing Ctrl-C.
In Python's signal module, signal.CTRL_C_EVENT (often shortened to CTRL_C) represents a special signal that corresponds to pressing the Ctrl+C key combination on your keyboard. This signal is typically used to interrupt a running program.
