本文实例讲述了Python实现从log日志中提取ip的方法。分享给大家供大家参考，具体如下：
log日志内容如下(myjob.log)：
124.90.53.68 - - [05/Feb/2018 11:37:07] "GET /favicon.ico HTTP/1.1" 404 - 61.148.245.145 - - [05/Feb/2018 12:37:44] "GET / HTTP/1.1" 200 - 61.148.245.145 - - [05/Feb/2018 12:37:44] "GET /apple-touch-icon-120x120-precomposed.png HTTP/1.1" 404 - 61.148.245.145 - - [05/Feb/2018 12:37:44] "GET /apple-touch-icon-120x120.png HTTP/1.1" 404 - 61.148.245.145 - - [05/Feb/2018 12:37:45] "GET /apple-touch-icon-precomposed.png HTTP/1.1" 404 - 61.148.245.145 - - [05/Feb/2018 12:37:45] "GET /apple-touch-icon.png HTTP/1.1" 404 - 61.148.245.145 - - [05/Feb/2018 12:37:45] "GET /static/favicon.ico HTTP/1.1" 200 - 101.226.33.218 - - [05/Feb/2018 13:07:39] "GET / HTTP/1.1" 200 - 101.226.33.219 - - [05/Feb/2018 13:09:46] "GET / HTTP/1.1" 200 - 101.226.33.219 - - [05/Feb/2018 13:09:46] "GET /static/youkulogo.png HTTP/1.1" 200 - 101.226.33.219 - - [05/Feb/2018 13:09:46] "GET /static/iqiyi.png HTTP/1.1" 200 - 101.226.33.219 - - [05/Feb/2018 13:09:46] "GET /static/qqlogo.png HTTP/1.1" 200 - 124.202.223.62 - - [05/Feb/2018 14:29:45] "GET / HTTP/1.1" 200 - 124.202.223.62 - - [05/Feb/2018 14:29:47] "GET /static/youkulogo.png HTTP/1.1" 200 - 124.202.223.62 - - [05/Feb/2018 14:29:48] "GET /static/qqlogo.png HTTP/1.1" 200 - 124.202.223.62 - - [05/Feb/2018 14:29:48] "GET /static/iqiyi.png HTTP/1.1" 200 - 124.202.223.62 - - [05/Feb/2018 14:29:49] "GET /static/favicon.ico HTTP/1.1" 200 -
提取ip:
# encoding: utf-8
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
import pandas as pd
import re
import time
import requests
time1=time.time()
######函数功能:能够提取ip地址，并且去重################
def read_file(input_file_name,output_file_name):
_fLog = open(input_file_name)
sep = 'n'
ip_list=[]
for each in _fLog:
ip=re.findall(r'(?
运行结果：
共解析ip个数:5
61.148.245.145

124.202.223.62
101.226.33.219
