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

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：
