How to close a thread from within?

For every client connecting to my server I spawn a new thread, like this:

# Create a new client
c = Client(self.server.accept(), globQueue[globQueueIndex], globQueueIndex, serverQueue )
                
# Start it
c.start()
                
# And thread it
self.threads.append(c)

Now, I know I can close all the threads using this code:

    # Loop through all the threads and close (join) them
    for c in self.threads:
        c.join()

But how can I close the thread from within that thread?

When you start a thread, it begins executing a function you give it (if you're extending threading.Thread, the function will be run()). To end the thread, just return from that function.

According to https://docs.python.org/3/library/threading.html">this</a>;, you can also call thread.exit(), which will throw an exception that will end the thread silently.

How about sys.exit() from the module sys.

If sys.exit() is executed from within a thread it will close that thread only.

This answer here talks about that: https://stackoverflow.com/questions/905189/why-does-sys-exit-not-exit-when-called-inside-a-thread-in-python

A little late, but I use a _is_running variable to tell the thread when I want to close. It's easy to use, just implement a stop() inside your thread class.

def stop(self):
  self._is_running = False

And in run() just loop on while(self._is_running)

If you want force stop your thread: thread._Thread_stop() For me works very good.
