How can I use signals with threads in Python?

You can use the signal module to handle signals in Python, but it has some limitations with threads. What do you want to achieve?

I want to handle a signal in a thread and perform a specific action when the signal is received.

You can set up a signal handler in the main thread and use a threading event to communicate with your worker threads. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

import signal
import threading
import time

# Create an event to signal threads
stop_event = threading.Event()

def worker():
    while not stop_event.is_set():
        print('Working...')
        time.sleep(1)

def signal_handler(signum, frame):
    print('Signal received!')
    stop_event.set()

# Set up signal handler
signal.signal(signal.SIGINT, signal_handler)

# Start the worker thread
thread = threading.Thread(target=worker)
thread.start()

# Wait for the thread to finish
thread.join()

Thanks! This is really helpful.
