python3 记录从ip.txt循环ping ip不通的时间和ip

Question

import os
import time

for line in open('ip.txt'):
line = int(line.replace('\n',''))
result=os.system('ping -n 1 -w 1 ip'% line)
time=time.time()
print(result)

    报错了，ip地址中既有数字，也有字符。别人的为啥都能ping，我的还要分开格式转换一下吗？太麻烦了吧。
     line = int(line.replace('\n',''))

ValueError: invalid literal for int() with base 10: '22.72.156.254'

Answer 1

line = int(line.replace('\n',''))
为什么要int，ip又不是数字
