如何在完成后自动退出PyQT QThread？

from PyQt5.QtCore import QThread, pyqtSignal

class MyThread(QThread):
    finished = pyqtSignal()

    def __init__(self):
        super().__init__()
        self.is_running = True

    def run(self):
        # 线程执行的逻辑
        while self.is_running:
            # 执行任务
            # ...

        self.finished.emit()

    def stop(self):
        self.is_running = False

# 主线程中的槽函数
def handle_finished():
    # 清理工作
    # ...

    # 退出线程
    thread.quit()
    thread.wait()

# 创建线程对象
thread = MyThread()
# 连接finished信号到槽函数
thread.finished.connect(handle_finished)
# 启动线程
thread.start()
