计时器

描述：用来执行定时任务（异步），点个赞不过分吧

# 计时器类(异步)
# time: 间隔时间(秒), 毫秒请使用小数(0.1xxxx)
# handle: 要进行的异步处理器(名称)
# arg: 异步处理器的参数(元组)
class setInteval(threading.Thread):
    def __init__(self, time, handle, arg):
        threading.Thread.__init__(self)
        self.time = time
        self.handle = handle
        self.arg = arg
        self.switch = True  # True 为计时器开启, False为计时器关闭
        self.start()

    def run(self):
        while True:
            if self.switch is True:
                try:
                    time.sleep(self.time)
                    self.handle(*(self.arg))
                except:
                    raise Exception("set interval error")
            else:
                break

    def clear_interval(self):
        self.switch = False

def test(a):
    print(a)

# 异步计时器测试
inteval = setInteval(1, test, ('aaaaaaaaaaaaaaaa',))
time.sleep(10)
inteval.clear_interval()
