apache脚本：
ips = {}
with open("/root/mail_access_log-20180629") as fh:
for line in fh:
ip = line.split(" ")[0]
if 6 < len(ip) <=15:
ips[ip] = ips.get(ip, 0) + 1
ip_num = []
for ipaddr,num in ips.items():
ip_num.append((ipaddr,num))
ip_num.sort(key=lambda x: x[1], reverse=True)
for ipaddr,num in ip_num[:20]:
print('IP地址为{}, 访问次数为{}'.format(ipaddr,num))nginx脚本：

print('IP地址为{}, 访问次数为{}'.format(ipaddr,num))python统计apache、nginx访问日志IP访问次数并且排序（显示前20条）
