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 -

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'("共解析ip个数:%s "% len(ids)
  ##写出数据到本地
  # 设置输出文件路径
  out = open(output_file_name, "a")
  # out.write("ip" + sep)
  for each in ids:
    print each
    out.write(each + sep)
  ##关闭连接
  out.close()
  _fLog.close()
  print "ip提取完毕~~"
####主函数################
if __name__ == '__main__':
  input_file_name = "C:/myjob.log"
  output_file_name = "c:/myjob.txt"
  read_file(input_file_name, output_file_name)
  time2 = time.time()
  print u'总共耗时:' + str(time2 - time1) + 's'

运行结果:

共解析ip个数:5
61.148.245.145
124.90.53.68
124.202.223.62
101.226.33.219
101.226.33.218
ip提取完毕~~
总共耗时:0.000999927520752s
Process finished with exit code 0

RTX 5090要首发 性能要翻倍!三星展示GDDR7显存

三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。

首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。

据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
