更新時間：2019年01月30日 12:01:46 作者：徐為波

這篇文章主要介紹了Python多線程處理,結合實例形式總結分析了Python單進程、多進程、多線程等相關操作技巧與注意事項,需要的朋友可以參考下

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(zhí)行完后，繼續(xù)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(zhí)行n=100次
  p = Process(target=sayhi,args=(n,))#調用函數(shù)def，若def函數(shù)里面有參數(shù)，就是使用args帶值賦值，若函數(shù)沒有參數(shù)的話就args()為空。
  p.start()
  p.join()#一個進程結束才會繼續(xù)下一個進程。如果注釋這句意思是一百個進程同時發(fā)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(zhí)行n=100次
  p = Process(target=sayhi,args=(n,))#調用函數(shù)def，若def函數(shù)里面有參數(shù)，就是使用args帶值賦值，若函數(shù)沒有參數(shù)的話就args()為空。
  p.start()
  p.join()#一個進程結束才會繼續(xù)下一個進程。如果注釋這句意思是一百個進程同時發(fā)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(zhí)行n=100次
  p = Process(target=sayhi,args=(n,))#調用函數(shù)def，若def函數(shù)里面有參數(shù)，就是使用args帶值賦值，若函數(shù)沒有參數(shù)的話就args()為空。
  p.start()
  #p.join()#一個進程結束才會繼續(xù)下一個進程。如果注釋這句意思是一百個進程同時發(fā)起
root@72132server:~/python/multiprocess#

運行情況

1）進程查看

2）腳本運行（1秒跑完）
