将单个ip转换为指定ip范围

# 需求：将192.168.1.254形式的ip转换为ip范围-> 192.168.1.1-192.168.1.254
import os

if __name__ == "__main__":
    with open('./target.txt','r',encoding='utf-8') as fp:
        lines = fp.readlines()
    list = []
    #将读取出来的内容存入列表
    for li in lines:
        list.append(li.rstrip())


    # 将ip的最后一位转换为1
    def ip_fun(ip):
        result = ip.split('.')
        result[3] = 1
        result_ip = '.'
        return result_ip.join('%s' % id for id in result)
    # 生成指定格式的ip范围，并写入指定的文件中
    with open('./ip.txt','w',encoding='utf-8') as fp1:
        for li1 in list:
            ip1 = li1
            ip2 = ip_fun(ip1)
            ip3 = ip2+'-'+ip1+'n'
            fp1.write(ip3)
