代码如下:
import _thread as thread stdoutmutex = thread.allocate_lock() exitmutexes = [thread.allocate_lock() for i in range(10)] def counter(myId, count): for i in range(count): print('1 %s -> %s' % (myId, stdoutmutex.locked())) stdoutmutex.acquire() print('2 %s -> %s' % (myId, stdoutmutex.locked())) print(stdoutmutex.locked()) print('[%s] => %s' % (myId, i)) stdoutmutex.release() exitmutexes[myId].acquire() for i in range(10): thread.start_new_thread(counter, (i, 10)) for mutex in exitmutexes: while not mutex.locked(): pass print('Main thread exiting')
问题: exitmutexes[myId].acquire()获得了锁的状态,while not mutex.locked(): pass 判断没有锁的话就继续执行,但我不知道什么时候释放的锁。 谢谢大家了!
![]() | 1 linw1995 2021-03-18 11:31:06 +08:00 想感知线程中函数的执行情况,可以用 Thread.join 。或者更细粒度的可以用 threading.Event |
![]() | 2 no1xsyzy 2021-03-18 13:20:21 +08:00 while not mutex.locked(): pass 这是判断没有锁就卡住,有锁继续执行。 |
3 shenyansycn OP @no1xsyzy 应该是有锁就卡住,没锁才执行 pass 吧 |
4 shenyansycn OP @no1xsyzy 我明白了,谢谢! |
