RT，查了Qt關于Pyside2的相關資料，對QThread的介紹使用還是override了run方法，并沒有Qt目前主推的moveToThread方法，我按照自己的理解使用Python寫了多執行緒。但是列印結果不正確，有誰能給找下問題，介紹下么？
MultiThreadTest：創建執行緒，信號槽觸發。
Worker：被移入新執行緒的類
具體代碼如下
Worker：

from PySide2.QtCore import Slot
from PySide2.QtCore import QObject
class Worker(QObject):
def __init__(self):
super().__init__()
# print('Worker.__init__ = ' + str(id(QThread.currentThread())))
@Slot()
def do_something(self):
# print('Worker.do_something = ' + str(threading.currentThread()))
print('Worker.do_something = ' + str(QThread.currentThread()))

from multithread.worker import Worker
class MultiThreadTest(QObject):
def __init__(self):
super().__init__()
self.__thread_a = QThread()
self.__worker = Worker()
self.send_msg.connect(self.__worker.do_something)
# pass
def start_multithread(self):
# print('MultithreadTest.start_multithread = ' + str(threading.currentThread()))
print('MultithreadTest.start_multithread = ' + str(QThread.currentThread()))
multi_thread = MultiThreadTest()
self.__worker.moveToThread(self.__thread_a.thread())
self.__thread_a.start()
# self.__thread_a.sleep(3)
# print('MultithreadTest.start_multithread = ' + str(threading.currentThread()))
print('MultithreadTest.start_multithread = ' + str(QThread.currentThread()))
# multi_thread.send_msg.emit()
self.send_msg.emit()
# print('MultithreadTest.start_multithread = ' + str(threading.currentThread()))
print('MultithreadTest.start_multithread = ' + str(QThread.currentThread()))
# 定義無引數信號槽
send_msg = Signal()
運行代碼：
#!/usr/bin/env python

from multithread.multithread_test import MultiThreadTest
start_01 = MultiThreadTest()
start_01.start_multithread()
運行結果：
MultithreadTest.start_multithread = <PySide2.QtCore.QThread object at 0x0000000002FE6408>
MultithreadTest.start_multithread = <PySide2.QtCore.QThread object at 0x0000000002FE62C8>
Worker.do_something = <PySide2.QtCore.QThread object at 0x0000000002FE62C8>
MultithreadTest.start_multithread = <PySide2.QtCore.QThread object at 0x0000000002FE62C8>
