我正在尝试创建一个多线程程序，它将运行一个线程三秒钟，然后暂停＆＃39;线程使用事件对象，等待几秒钟，然后重复该过程。这是我的代码：
import threading
import time
counter = 1
def control():
global counter
test_event.wait()
while(test_event.is_set()):
print 'waiting 3 seconds'
time.sleep(3)
event.set()
time.sleep(3)
event.clear()
if(counter == 1):
counter = counter - 1
def function():
global counter
event.wait()
while (event.is_set()):
test_event.clear()
print 'event is set to high'
time.sleep(1)
print 'event is set to low'
test_event.set()
event = threading.Event()
test_event = threading.Event()
t1 = threading.Thread(target = control)
t2 = threading.Thread(target = function)
t1.start()
t2.start()
while(counter == 1):
test_event.set()
我想要的输出应该是这样的：
waiting 3 seconds
event is set to high
event is set to high
event is set to high
event is set to low
waiting 3 seconds
event is set to high
....
....
and that keeps repeating.
我目前收到的输出是：
waiting three seconds
event is set to high
event is set to high
event is set to high
waiting 3 seconds
event is set to low
waiting 3 seconds
waiting 3 seconds
waiting 3 seconds
...
...
and that keeps repeating.
有人可以检测到我搞砸的地方，并可能提供任何建议让我解决？我似乎无法弄清楚我做错了什么。
P.S。我知道这段代码的构造可能很差，但我对多线程完全不熟悉...提前抱歉！
