ip_list = ['192.168.1.100', '192.168.10.3', '192.168.8.1']
ip_list.sort(lambda x,y: cmp(''.join( [ i.rjust(3, '0') for i in x.split('.')] ), ''.join( [ i.rjust(3, '0') for i in y.split('.')] ) ) )
结果
['192.168.1.100', '192.168.8.1', '192.168.10.3']
方法二：
转换成 int 型，用 int 来比较
import struct
import socket
def ip2int(addr):
return struct.unpack("!I", socket.inet_aton(addr))[0]
def int2ip(addr):
return socket.inet_ntoa(struct.pack("!I", addr))
ip_list = ['192.168.1.100', '192.168.10.3', '192.168.8.1']
# 构建 int_ip:ip 形式的 key:value, 并对 key 排序
ip_unsorted_dict = {}
for ip in ip_list:
int_ip = ip2int(ip)
ip_unsorted_dict[int_ip] = ip
keys = ip_unsorted_dict.keys()
keys.sort()
ip_sorted_list=[]
for key in keys:
ip_sorted_list.append(ip_unsorted_dict[key])
print ip_sorted_list
