python队列join
如果要让一个任务队列按照顺序进行,则必须使用join,代码如下:
''' Created on Dec 23, 2013 @author: long ''' import threading from threading import Thread import time class Thread1(Thread): ''' classdocs ''' def __init__(self,thread_name): ''' Constructor ''' Thread.__init__(self,name=thread_name) def run(self): ''' run method ''' count = 0 while True: print ('thread--',self.getName(),",count:",count) time.sleep(0.5) count = count + 1 if count > 10: break def main(): for y in range(1, 3): thread1 = Thread1('longthread' + str(y)) thread1.start() if thread1.isAlive(): thread1.join() for i in range(50): print ('main:', i) if __name__ == "__main__": main()
结果是先执行名为'longthread1',再'longthread2',再是主进程,所以thread1.join()的意思是等thread1执行完,再去执行其他线程。
I will be a better man
