Python threading: can I sleep on two threading.Event()s simultaneously?

Question

If I have two threading.Event() objects, and wish to sleep until either one of them is set, is there an efficient way to do that in python? Clearly I could do

Answer 1

def wait_for_event_timeout(*events):
    while not all([e.isSet() for e in events]):
        #Check to see if the event is set. Timeout 1 sec.
        ev_wait_bool=[e.wait(1) for e in events]
        # Process if all events are set. Change all to any to process if any event set
        if all(ev_wait_bool):
            logging.debug('processing event')
        else:
            logging.debug('doing other work')


e1 = threading.Event()
e2 = threading.Event()

t3 = threading.Thread(name='non-block-multi',
                      target=wait_for_event_timeout,
                      args=(e1,e2))
t3.start()

logging.debug('Waiting before calling Event.set()')
time.sleep(5)
e1.set()
time.sleep(10)
e2.set()
logging.debug('Event is set')
