Stopping python using ctrl c смотреть онлайн

In this tutorial, you will learn how to gracefully stop a Python program using the Ctrl+C keyboard interrupt signal. Ctrl+C is a common way to halt the execution of a running Python script or program when you need to terminate it manually. We will cover how to handle this signal and perform cleanup operations if needed.
Before we start, ensure that you have Python installed on your system. You can download Python from the official Python website.
When you press Ctrl+C in the terminal while a Python program is running, it sends a KeyboardInterrupt signal to the Python process. By default, this will cause your program to terminate immediately. However, you can catch this signal and handle it gracefully by using the signal module.
Here's a step-by-step guide with a code example:
First, import the signal module, which allows you to handle signals like Ctrl+C:
Next, define a function that will be called when the Ctrl+C signal is received. This function is known as the "signal handler."
In the signal_handler function, you can add any cleanup code or actions you want to perform before the program exits.
Now, you need to associate the signal_handler function with the Ctrl+C signal using the signal.signal function. This tells Python what to do when a Ctrl+C signal is received.
In this case, we are associating the signal_handler function with the SIGINT signal, which is the signal sent when Ctrl+C is pressed.
Now, run your Python program as you normally would. When you press Ctrl+C, it will trigger the signal_handler function and execute any cleanup code you specified before exiting.
Here's a complete example:
