python - 可停止线程错误

Question

我正在创建一个可停止线程类:

import threading

class StoppableThread(threading.Thread):
    """Thread class with a stop() method. The thread itself has to check
    regularly for the stopped() condition."""

    def __init__(self):
        super(StoppableThread, self).__init__()
        self._stop = threading.Event()

    def stop(self):
        self._stop.set()

    def stopped(self):
        return self._stop.isSet()

但是当我像这样创建对象时:

我收到此错误:

Traceback (most recent call last):
  File "./myFile.py", line 81, in <module>
    aObject = StoppableThread(target, args=("foo", "bar",)))
TypeError: __init__() got an unexpected keyword argument 'args'

提前谢谢您。

Answer 1

您已经重写了 init 方法，并且那里没有“args”参数。

你必须做这样的事情:

 def __init__(self, group=None, target=None, name=None, args=(), kwargs={}):
        super(StoppableThread, self).__init__(group, target, name, args, kwargs)
        self._stop = threading.Event()
