What are common signals in Python?

Common signals in Python include SIGINT, SIGTERM, and SIGHUP. They are used for inter-process communication.

How can I handle these signals in my Python code?

You can use the signal module to handle signals. For example, you can define a handler function and use signal.signal() to associate it with a specific signal.

Can you show me a code example?

Sure! Here's a simple example:

import signal
import time

def handler(signum, frame):
    print('Signal received:', signum)

signal.signal(signal.SIGINT, handler)

while True:
    time.sleep(1)

What happens if I don't handle signals?

If you don't handle signals, the default behavior will occur, which may terminate your program or cause it to exit unexpectedly.
