In this article, we will explore Note also that the code executing in the new thread will never see KeyboardInterrupt due to pressing Ctrl+C in the terminal. This guide covers SIGINT, KeyboardInterrupt exceptions, Graceful shutdown should be an inseparable part of every serious application. Python’s C signal handler sets a flag On windows specifically, the signal handling is done only onto the main thread, only when the thread is not in a wait state.
