Python3添加IP地址的最后一个八位位组

Question

I'm parsing a file and one of the columns is the subnet for example 192.168.0.0/24. I would like to take that subnet and just add 3 to the last octet and with the end result of 192.168.0.3 without the /24. I was able to open the file for reading, split it into ',' locate the subnet and add but I can't produce 192.168.0.3 I only produce 3.

import re

file=open('/home/lab01/clients/a/2018/automation/Production_VRF','r')
for items in file:
 _gw=(items.split(',')[2])
 Var6=re.split(r'[./]',_gw)
 Var7=(Var6[3])
 vip=sum=int(Var7)+3
 print(vip)

Thank you!

您应该在Var6中添加前三个元素的串联和已指定的值：

ip = Var6[0]+"."+Var6[1]+"."+Var6[2]+"."+str(vip)
