努力向前走一步，离梦想就更近一步。错过现在就等于糟蹋未来。生活就是那样，不留一丝余地，活下去似乎都需要很大的勇气。
本文实例讲述了Python多线程处理操作。分享给大家供大家参考，具体如下：
python — 多线程处理
1、一个进程执行完后，继续下一个进程
root@72132server:~# cd /root/python/multiprocess/ root@72132server:~/python/multiprocess# ls multprocess.py root@72132server:~/python/multiprocess# cat multprocess.py #!/usr/bin/python # --*-- coding:utf-8 --*-- from multiprocessing import Process,Lock#启用多进程，与进程锁 import time,os def sayhi(i): print 'hello world!!!', i time.sleep(10) #lock = Lock() for n in range(100):#执行n=100次 p = Process(target=sayhi,args=(n,))#调用函数def，若def函数里面有参数，就是使用args带值赋值，若函数没有参数的话就args()为空。 p.start() p.join()#一个进程结束才会继续下一个进程。如果注释这句意思是一百个进程同时发起 root@72132server:~/python/multiprocess#
运行情况：
1）进程查看
root@72132server:~# cd /root/python/multiprocess/ root@72132server:~/python/multiprocess# ls multprocess.py root@72132server:~/python/multiprocess# vi multprocess.py root@72132server:~/python/multiprocess# ps -ef | grep multi root 24064 23930 0 20:45 pts/3 00:00:00 grep multi root@72132server:~/python/multiprocess# ps -ef | grep multi root 24066 23930 0 20:45 pts/3 00:00:00 grep multi root@72132server:~/python/multiprocess# ps -ef | grep multi root 24069 23930 0 20:45 pts/3 00:00:00 grep multi root@72132server:~/python/multiprocess# ps -ef | grep multi root 24071 23930 0 20:45 pts/3 00:00:00 grep multi root@72132server:~/python/multiprocess# ps -ef | grep multi root 24073 23930 0 20:46 pts/3 00:00:00 grep multi root@72132server:~/python/multiprocess# ps -ef | grep multi root 24075 23930 0 20:46 pts/3 00:00:00 grep multi root@72132server:~/python/multiprocess#
2）脚本运行
root@72132server:~/python/multiprocess# vi multprocess.py root@72132server:~/python/multiprocess# python multprocess.py hello world!!! 0 hello world!!! 1 hello world!!! 2 hello world!!! 3 hello world!!! 4 hello world!!! 5 hello world!!! 6 hello world!!! 7 hello world!!! 8 hello world!!! 9 hello world!!! 10 hello world!!! 11
2、100个进行同时运行
root@72132server:~/python/multiprocess# ls multprocess.py root@72132server:~/python/multiprocess# cat multprocess.py #!/usr/bin/python # --*-- coding:utf-8 --*-- from multiprocessing import Process,Lock#启用多进程，与进程锁 import time,os def sayhi(i): print 'hello world!!!', i time.sleep(10) #lock = Lock() for n in range(100):#执行n=100次 p = Process(target=sayhi,args=(n,))#调用函数def，若def函数里面有参数，就是使用args带值赋值，若函数没有参数的话就args()为空。 p.start() p.join()#一个进程结束才会继续下一个进程。如果注释这句意思是一百个进程同时发起 root@72132server:~/python/multiprocess# root@72132server:~/python/multiprocess# vi multprocess.py root@72132server:~/python/multiprocess# cat multprocess.py #!/usr/bin/python # --*-- coding:utf-8 --*-- from multiprocessing import Process,Lock#启用多进程，与进程锁 import time,os def sayhi(i): print 'hello world!!!', i time.sleep(10) #lock = Lock() for n in range(100):#执行n=100次 p = Process(target=sayhi,args=(n,))#调用函数def，若def函数里面有参数，就是使用args带值赋值，若函数没有参数的话就args()为空。 p.start() #p.join()#一个进程结束才会继续下一个进程。如果注释这句意思是一百个进程同时发起 root@72132server:~/python/multiprocess#
运行情况
1）进程查看
2）脚本运行（1秒跑完）
root@72132server:~/python/multiprocess# python multprocess.py hello world!!! 0 hello world!!! 2 hello world!!! 3 hello world!!! 5 hello world!!! 7 hello world!!! 8 hello world!!! 6 hello world!!! 9 hello world!!! 10 hello world!!! 11 hello world!!! 14 hello world!!! 4 hello world!!! 15 hello world!!! 16 hello world!!! 1 hello world!!! 13 hello world!!! 18 hello world!!! 20 hello world!!! 19 hello world!!! 21 hello world!!! 12 hello world!!! 17 hello world!!! 23 hello world!!! 24 hello world!!! 26 hello world!!! 27 hello world!!! 22 hello world!!! 29 hello world!!! 31 hello world!!! 32 hello world!!! 33 hello world!!! 34 hello world!!! 28 hello world!!! 25 hello world!!! 30 hello world!!! 35 hello world!!! 36 hello world!!! 39 hello world!!! 41 hello world!!! 37 hello world!!! 40 hello world!!! 42 hello world!!! 43 hello world!!! 46 hello world!!! 47 hello world!!! 48 hello world!!! 38 hello world!!! 44 hello world!!! 45 hello world!!! 50 hello world!!! 51 hello world!!! 53 hello world!!! 54 hello world!!! 55 hello world!!! 57 hello world!!! 49 hello world!!! 58 hello world!!! 59 hello world!!! 60 hello world!!! 61 hello world!!! 62 hello world!!! 63 hello world!!! 64 hello world!!! 65 hello world!!! 66 hello world!!! 67 hello world!!! 68 hello world!!! 69 hello world!!! 56 hello world!!! 70 hello world!!! 52 hello world!!! 71 hello world!!! 72 hello world!!! 73 hello world!!! 76 hello world!!! 74 hello world!!! 78 hello world!!! 79 hello world!!! 80 hello world!!! 82 hello world!!! 77 hello world!!! 83 hello world!!! 84 hello world!!! 85 hello world!!! 86 hello world!!! 87 hello world!!! 81 hello world!!! 91 hello world!!! 75 hello world!!! 89 hello world!!! 92 hello world!!! 88 hello world!!! 90 hello world!!! 93 hello world!!! 95 hello world!!! 94 hello world!!! 96 hello world!!! 98 hello world!!! 9
