本文實例講述了python使用線程封裝的一個簡單定時器類。分享給大家供大家參考。具體實現方法如下：
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 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()希望本文所述對大家的Python程序設計有所幫助。
