pyqt Using threads with PyQt The worker model

Example

# this method can be anything and anywhere as long as it is accessible for connection
@pyqtSlot()
def run_on_complete():
   
    pass

# An object containing methods you want to run in a thread
class Worker(QObject):
    complete = pyqtSignal()
    
    @pyqtSlot()
    def a_method_to_run_in_the_thread(self):
        # your code
        
        # Emit the complete signal
        self.complete.emit() 

# instantiate a QThread
thread = QThread()
# Instantiate the worker object
worker = Worker()
# Relocate the Worker object to the thread
worker.moveToThread(thread)
# Connect the 'started' signal of the QThread to the method you wish to run
thread.started.connect(worker.a_method_to_run_in_the_thread)
# connect to the 'complete' signal which the code in the Worker object emits at the end of the method you are running
worker.complete.connect(run_on_complete)
# start the thread (Which will emit the 'started' signal you have previously connected to)
thread.start()
