what is received through recv() are bytes but QListWidget requires string so the solution is to convert it using decode().
But your code has another hidden error(it seems to me that the author of the tutorial knows little about GUI so I recommend looking for another tutorial), the GUI can not be updated from another thread, that is forbidden by Qt, so the solution is to use signals or as in this case use @pyqtSlot() with QMetaObject::invokeMethod().

On the other hand I recommend using QTcpSocket since with its use there is no need for threads, in the this link you can find several examples.

what is received through recv() are bytes but QListWidget requires string so the solution is to convert it using decode().
But your code has another hidden error(it seems to me that the author of the tutorial knows little about GUI so I recommend looking for another tutorial), the GUI can not be updated from another thread, that is forbidden by Qt, so the solution is to use signals or as in this case use @pyqtSlot() with QMetaObject::invokeMethod().
