导致“必须以实例作为第一个参数调用未绑定方法__init __()"的原因是什么?从这个Python代码? [英] What is causing "unbound method __init__() must be called with instance as first argument" from this Python code?

问题描述

我上了这个课:

from threading import Thread 
import time

class Timer(Thread): 
    def __init__(self, interval, function, *args, **kwargs): 
        Thread.__init__() 
        self.interval = interval 
        self.function = function 
        self.args = args 
        self.kwargs = kwargs 
        self.start()

    def run(self): 
        time.sleep(self.interval) 
        return self.function(*self.args, **self.kwargs) 

并使用以下脚本对其进行调用:

and am calling it with this script:

    import timer 
    def hello():
        print \"hello, world
    t = timer.Timer(1.0, hello)
    t.run()

并收到此错误，我不知道为什么:unbound method __init__() must be called with instance as first argument

and get this error and I can't figure out why: unbound method __init__() must be called with instance as first argument

推荐答案

您正在做

Thread.__init__() 

使用:

Thread.__init__(self) 

或者，而是使用super()
