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.
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.

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.
24 wrz 2024 · Syntax. To catch a KeyboardInterrupt in Python, you can use a try-except block. The KeyboardInterrupt exception is raised when the user presses Ctrl+C, and you can handle it gracefully by incorporating the following syntax: try: # Code that may raise KeyboardInterruptexcept KeyboardInterrupt: # Code to handle the KeyboardInterrupt.
The “Signal Interrupt” or SIGINT signal is raised in a program when the user presses Ctrl-C. This has the effect of interrupting and often terminating a Python program. The SIGINT signal can be used to terminate asyncio programs as well, and we can use a custom signal handler function to perform cleanup activities before the asyncio program ...
