 import threading
 import time
 mylock = threading.RLock()
 num=0  

 class myThread(threading.Thread):
     def __init__(self, name):
         threading.Thread.__init__(self)
         self.t_name = name  

     def run(self):
         global num
         while True:
             mylock.acquire()
             print '\nThread(%s) locked, Number: %d'%(self.t_name, num)
             if num>=10:
                 mylock.release()
                 print 'num >=10 thread over!'
                 break
             num+=1
             print '\nThread(%s) released, Number: %d'%(self.t_name, num)
             time.sleep(1)
             mylock.release()  

 def test():
     thread1 = myThread('A')
     thread2 = myThread('B')
     thread1.start()
     thread2.start()  

 if __name__== '__main__':
     test()  

运行结果:
