功能 http://netaddr.readthedocs.io/en/latest/tutorial_03.html 将CIDR地址与IP范围相互转化 Convert CIDR to IP range or vice versa. 223.80.97.0/24 ->> 223.80.97.0-223.80.97.255 223.80.97.0-223.80.97.255 ->> 223.80.97.0/24 安装 pip install netaddr Demo 部分代码示例 f
python基础 生成式 列表生成式 格式 [表达式 for 表达式 in 迭代对象 (可加判断)] 原: res1 = [] for i in range(1,5): res1.append(i) print(res1) 改: res2 = [i for i in range(1,5)] print(res2) 字典生成式 格式 {key:value for 表达式 in 迭代对象 (可加判断)} a = "adasdsasad" b = "asdasdasdg"
Python实现比较两个列表(list)范围 有一道题: 比较两个列表范围,如果包含的话,返回TRUE,否则FALSE. 详细题目如下: Create a function, this function receives two lists as parameters, each list indicates a scope of numbers, the function judges whether list2 is included in list1. Function signature
java查看本机hostName可代表的ip列表 import java.net.InetAddress; public class ent { public static void main(String[] args) { String[] s = getAllLocalHostIP(); } public static String[] getAllLocalHostIP() { String[] ret = null; try { String hostName = InetAddres
