Python方法oslo_service.loopingcall.LoopingCallDone代码示例

demo:

from oslo_service import loopingcall

def _wait_for_image_state():
    global num
    num =
    def _wait_for_state():
        global num
        print num
        num = num +
        if num == :
            raise loopingcall.LoopingCallDone()

    timer = loopingcall.FixedIntervalLoopingCall(_wait_for_state)
    timer.start(interval=0.5).wait()

_wait_for_image_state()
