本文实例讲述了python使用线程封装的一个简单定时器类。分享给大家供大家参考。具体实现方法如下：

from threading import Timer class MyTimer: def __init__(self): self._timer= None self._tm = None self._fn = None def _do_func(self): if self._fn: self._fn() self._do_start() def _do_start(self): self._timer = Timer(self._tm, self._do_func) self._timer.start() def start(self, tm, fn): self._fn = fn self._tm = tm self._do_start() def stop(self): try: self._timer.cancel() except: pass def hello(): from datetime import datetime print("hello world!", datetime.now()) if __name__ == '__main__': mt = MyTimer() mt.start(2, hello) for i in range(10): import time time.sleep(1) mt.stop()

希望本文所述对大家的Python程序设计有所帮助。
