本文實例講述了Python多線程處理操作。分享給大家供大家參考,具體如下:
python — 多線程處理
1、一個進程執行完后,繼續下一個進程
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#啟用多進程,與進程鎖 import time,os def sayhi(i): print 'hello world!!!', i time.sleep(10) #lock = Lock() for n in range(100):#執行n=100次 p = Process(target=sayhi,args=(n,))#調用函數def,若def函數里面有參數,就是使用args帶值賦值,若函數沒有參數的話就args()為空。 p.start() p.join()#一個進程結束才會繼續下一個進程。如果注釋這句意思是一百個進程同時發起 root@72132server:~/python/multiprocess#
運行情況:
1)進程查看
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)腳本運行
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個進行同時運行
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#啟用多進程,與進程鎖 import time,os def sayhi(i): print 'hello world!!!', i time.sleep(10) #lock = Lock() for n in range(100):#執行n=100次 p = Process(target=sayhi,args=(n,))#調用函數def,若def函數里面有參數,就是使用args帶值賦值,若函數沒有參數的話就args()為空。 p.start() p.join()#一個進程結束才會繼續下一個進程。如果注釋這句意思是一百個進程同時發起 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#啟用多進程,與進程鎖 import time,os def sayhi(i): print 'hello world!!!', i time.sleep(10) #lock = Lock() for n in range(100):#執行n=100次 p = Process(target=sayhi,args=(n,))#調用函數def,若def函數里面有參數,就是使用args帶值賦值,若函數沒有參數的話就args()為空。 p.start() #p.join()#一個進程結束才會繼續下一個進程。如果注釋這句意思是一百個進程同時發起 root@72132server:~/python/multiprocess#
運行情況
1)進程查看
2)腳本運行(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
