本文实例讲述了Python统计日志中每个IP出现次数的方法。分享给大家供大家参考。具体如下：

这脚本可用于多种日志类型,本人测试MDaemon的all日志文件大小1.23G左右,分析用时2~3分钟

代码很简单,很适合运维人员,有不足的地方请大家指出哦

#-*- coding:utf-8 -*-

import re,time

def mail_log(file_path):

global count

log=open(file_path,'r')

C=r'\.'.join([r'\d{1,3}']*4)

find=re.compile(C)

count={}

for i in log:

for ip in find.findall(i):

count[ip]=count.get(ip,1)+1

if __name__ == '__main__':

print time.clock()

num=0

mail_log(r'e:\MDaemon-20110329-all.log')

R=count.items()

for i in R:

if i[1]>0: #提取出现次数大于0的IP

print i

num+=1

print '符合要求数量：%s耗时(%s)'%(num,time.clock())

输出结果如下：
