What are some examples of signals in Python?

In Python, signals are used for communication between different parts of a program. For example, in the signal module, you can use signals to handle asynchronous events.

Can you show me a simple code example?

Sure! Here's a basic example:

import signal
import time

# Define a signal handler function
def handler(signum, frame):
    print('Signal received:', signum)

# Register the signal handler
signal.signal(signal.SIGINT, handler)

# Wait for a signal
print('Waiting for a signal...')
while True:
    time.sleep(1)

What does the SIGINT signal do?

SIGINT is a signal sent to a process to interrupt it, typically initiated by the user pressing Ctrl+C in the terminal.

Are there other signals I can use?

Yes, there are several signals like SIGTERM, SIGQUIT, and SIGUSR1, each serving different purposes in process control.
