How to run a function on a thread, PYQT?

Question

Python

The problem is this:
There is a function, it needs to be run in a thread, I do it like this:

self.mltpr = threading.Thread(target=self.startFunction, args=())
self.mltpr.start()

From time to time I get an error - QWidget::repaint: Recursive repaint detected I
also tried to run it through _thread, then it works, but I read somewhere that it is impossible to do this.
How to run a function in a separate thread without creating an additional class to work with the thread?
(I know how to use Google)
