pythonthread并发且顺序运行示例

代码如下:

#-*- coding:utf-8 -*- import threading import time def fun(name, ls_name, front_thread = none): ””’ 线程启动函数 通过front_thread来使用线程有序的运行 ”’ time.clock() time.sleep(2) # 如果front_thread存在,则在front_thread运行完成后,才运行当前线程 if front_thread != none: front_thread.join() ls_name.append(name) print “thread %s : %s”% (name, time.clock()) if __name__ == ‘__main__’: ls_result_name = [] ls_thread = [] time.clock() # 逐一启动1000个线程 for i in range(0,10): if len(ls_thread) == 0: t = threading.thread(target=fun, args=(i,ls_result_name,none)) else: t = threading.thread(target=fun, args=(i,ls_result_name,ls_thread[-1])) t.start() ls_thread.append(t) # 等待所有线程结束 for t in ls_thread: t.join() print ‘ls_result_name:’, ls_result_name print “main thread:%s” % time.clock()

运行结果为: thread 0 : 1.99962006344 thread 1 : 2.00000866032 thread 2 : 2.00059113658 thread 3 : 2.00080345407 thread 4 : 2.00100068584 thread 5 : 2.00119456523 thread 6 : 2.00138593033 thread 7 : 2.00166753037 thread 8 : 2.00211758757 thread 9 : 2.0024776892 ls_result_name: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] main thread:2.003211302 线程更明细的使用可参考: http://docs.python.org/library/threading.html time.clock模块的更详细介绍可参考: http://blog.csdn.net/kiki113/archive/2009/03/28/4033017.aspx
