How to correctly terminate a QThread in pyqt5?

Question

PyQt

There is a program for pyqt5. It has a thread (qthread), in which it is necessary to perform some action with a certain peredachnostyu. I used QThread.msleep to define this period, and a flag to exit the while loop.
But if the period is long, then it will take a long time to exit the loop, and I want to terminate it as soon as I click on the button in the GUI (but don't kill it, start it again soon).
The source code here is pretty standard, I need more ideas.

Answer 1

Split QThread.msleep into several small segments and check whether to exit after each
Through the loop
