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。
