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：
