本文实例讲述了Python实现根据IP地址和子网掩码算出网段的方法。分享给大家供大家参考。具体如下：

该代码在Linux环境2.6.6python版本测试通过！

#!/usr/bin/env python#_*_encoding:utf-8_*_#Input your ip address and netmask to figure out your network .#申明：此脚本为交互式，默认情况下请执行python network.pyfrom IPy import IPinput_IP = raw_input('请输入ip地址:')list1 = input_IP.split('.')if len(list1) != 4: print "您输入的ip地址不合法，请重新输入！" exit()for i in list1: if i.isdigit() == True and int(i) >=0 and int(i) <= 255: pass else: print "您输入的ip地址不合法，请重新输入！" exit()input_Netmask = raw_input('请输入子网掩码:')list2 = input_Netmask.split('.')if len(list2) != 4: print "您输入的子网掩码不合法，请重新输入!" exit()for i in list2: if i.isdigit() == True and int(i) >=0 and int(i) <= 255: pass else: print "您输入的子网掩码不合法，请重新输入!" exit()print "您所在的网段为:%s" % (IP(input_IP).make_net(input_Netmask))

希望本文所述对大家的Python程序设计有所帮助。
