Python 多线程 锁 问题
程序代码：
import threading
VALUE = 0
gLOCK = threading.Lock()
class MyThread(threading.Thread):
def __init__(self, loop_times):
super().__init__()
self.loop_times = loop_times
def run(self):
global VALUE
for i in range(self.loop_times):
gLOCK.acquire()
VALUE += 1
gLOCK.release()
print(self.loop_times, self.name, VALUE)
if __name__ == '__main__':
for i in range(2):
MyThread(1000000).start()
我想知道为什么这样使用锁得不到期望的预期结果:
1000000 Thread-1 1000000
1000000 Thread-2 2000000
