python整理C段ip脚本

用python实现IP地址整为C段：

#!/usr/bin/python# -*- coding:utf-8 -*-import re# def cleanCLRFspace(content):# 	noCLContext = content.replace('\n','')# 	noSpaceCLRFcontext = noCLContext.strip()# 	return noSpaceCLRFcontextdef readFile():ipf = open('./content.txt','r')return ipfdef getLineIP(ipf):ipList = set()texts = ipf.readlines()for text in texts:ips = re.findall(r'\d+\.\d+?\.\d+?\.\d+?',text)for ip in ips:ipList.add(ip)return ipListdef ip2c(ipNoDup):ipset = set()for ip in ipNoDup:ipset.add(re.findall(r'\d+?\.\d+?\.\d+?\.',ip)[0] + '0/24')iplist = list(ipset)iplist.sort()return iplistdef saveContext(s):wfile = open('./result.txt','w')for i in s:wfile.write(i+'\n')wfile.close()if __name__ == '__main__':ipf = readFile()ipList = getLineIP(ipf)iplist = ip2c(ipList)saveContext(iplist)
