You can use the functions in Python's built-in signal module to set up signal handlers in python. Specifically the signal.signal(signalnum, handler) function is used to register the handler function for signal signalnum .
I want to know if it's possible to catch a Control-C in python in the following manner: if input != contr-c: #DO THINGS. else: #quit. I've read up on stuff with try and except KeyboardInterrupt but they're not working for me. python. error-handling. keyboard-events.
25 maj 2019 · To catch a signal in Python, you need to register the signal you want to listen for and specify what function should be called when that signal is received. This example shows how to catch a SIGINT and exit gracefully. from signal import signal, SIGINT. from sys import exit.
27 lut 2024 · This code snippet sets up a signal handler that catches SIGINT signals (typically triggered by a Ctrl+C interrupt). When such a signal occurs, the sigint_handler function is called, which prints a message and exits the program cleanly.
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.
3 lis 2023 · Learn how to send a Ctrl-C signal to interrupt and stop Python scripts. This guide covers SIGINT, KeyboardInterrupt exceptions, simulating Ctrl-C with os.kill(), handling exceptions gracefully, and real-world examples like stopping loops and servers.
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.
