如何让多线程python程序响应Ctrl+C按键事件?
Edit:代码是这样的:
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<self.total:
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()
我尝试删除所有线程上的 join() 但它仍然不起作用。是因为每个线程的 run() 过程中的锁段吗?
Edit:上面的代码应该可以工作,但是当当前变量在 5,000-6,000 范围内时它总是中断,并出现如下错误
