python停止线程_如何终止一个多线程python程序？

如何使多线程python程序响应Ctrl+C键事件？

代码如下：import threading

current = 0

class MyThread(threading.Thread):

def __init__(self, total):

threading.Thread.__init__(self)

self.total = total

def stop(self):

self._Thread__stop()

def run(self):

global current

while current

lock = threading.Lock()

lock.acquire()

current+=1

lock.release()

print current

if __name__=='__main__':

threads = []

thread_count = 10

total = 10000

for i in range(0, thread_count):

t = MyThread(total)

t.setDaemon(True)

threads.append(t)

for i in range(0, thread_count):

threads[i].start()

我试图删除所有线程上的join（），但它仍然不起作用。是否因为每个线程的run（）过程中的锁段？

上面的代码应该可以工作，但是当当前变量在5,000-6,000范围内并且通过如下错误时它总是中断Exception in thread Thread-4 (most likely raised during interpreter shutdown):

Traceback (most recent call last):

File "/usr/lib/python2.5/threading.py", line 486, in __bootstrap_inner

File "test.py", line 20, in run
