<p style="color: grey"> Python recipe 82965 by <a href="/recipes/users/136936/">Jacob Hallén</a> (<a href="/recipes/tags/threads/">threads</a>). </p> <p>This recipe shows the easiest way of handling access to sockets, serial ports and other asynchronous I/O ports while running a Tkinter based GUI. It allows for a worker thread to block in a select(). Whenever something arrives it will received and inserted in a queue. The main (GUI) thread then polls the queue 10 times per second (often enough so the user will not notice any significant delay), and processes all messages that have arrived.</p>
