Python-如何优雅地处理SIGTERM信号？

基于类的干净使用解决方案：

import signalimport timeclass GracefulKiller:  kill_now = False  def __init__(self):    signal.signal(signal.SIGINT, self.exit_gracefully)    signal.signal(signal.SIGTERM, self.exit_gracefully)  def exit_gracefully(self,signum, frame):    self.kill_now = Trueif __name__ == '__main__':  killer = GracefulKiller()  while not killer.kill_now:    time.sleep(1)    print("doing something in a loop ...")  print "End of the program. I was killed gracefully :)"
