這篇文章主要介紹了Python多線程處理,結(jié)合實(shí)例形式總結(jié)分析了Python單進(jìn)程、多進(jìn)程、多線程等相關(guān)操作技巧與注意事項(xiàng),需要的朋友可以參考下

本文實(shí)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(gè)進(jìn)程執(zhí)行完后，繼續(xù)下一個(gè)進(jìn)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(jìn)程，與進(jìn)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(diào)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(méi)有參數(shù)的話就args()為空。
  p.start()
  p.join()#一個(gè)進(jìn)程結(jié)束才會(huì)繼續(xù)下一個(gè)進(jìn)程。如果注釋這句意思是一百個(gè)進(jìn)程同時(shí)發(fā)起
root@72132server:~/python/multiprocess#

運(yùn)行情況：

1）進(jìn)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(yùn)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(gè)進(jìn)行同時(shí)運(yùn)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(jìn)程，與進(jìn)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(diào)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(méi)有參數(shù)的話就args()為空。
  p.start()
  p.join()#一個(gè)進(jìn)程結(jié)束才會(huì)繼續(xù)下一個(gè)進(jìn)程。如果注釋這句意思是一百個(gè)進(jìn)程同時(shí)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(jìn)程，與進(jìn)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(diào)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(méi)有參數(shù)的話就args()為空。
  p.start()
  #p.join()#一個(gè)進(jìn)程結(jié)束才會(huì)繼續(xù)下一個(gè)進(jìn)程。如果注釋這句意思是一百個(gè)進(jìn)程同時(shí)發(fā)起
root@72132server:~/python/multiprocess#

運(yùn)行情況

1）進(jìn)程查看
