Pyside2 threads-CodePudding

RT, check the Qt about Pyside2 related information, with the introduction of the QThread use or override the run method, no Qt main moveToThread method at present, I wrote a multithreaded according to own understanding to use Python, but the print result is not correct, have who can give me to find the problem, introduce?
MultiThreadTest: create a thread, groove trigger signal,
Worker: being moved to the new thread class
Specific code below
