读取主机名列表并解析为 IP 地址

Question

我正在尝试读取纯文本文件并解析每个 IP 地址，并且（目前）只是将它们吐回到屏幕上。

import socket

f = open("test.txt")
num_line = sum(1 for line in f)
f.close()

with open("test.txt", "r") as ins:
        array = []
        for line in ins:
                array.append(line)

for i in range(0,num_line):
        x = array[i]
        print x 
        data = socket.gethostbyname_ex(x)
        print data

目前我得到以下信息：

me@v:/home/# python resolve-list2.py
test.com

Traceback (most recent call last):
  File "resolve-list2.py", line 15, in <module>
    data = socket.gethostbyname_ex(x)
socket.gaierror: [Errno -2] Name or service not known

谷歌搜索该错误似乎对我没有帮助......该文本文件目前仅包含一行（test.com），但即使使用多行/不同主机，我也会收到相同的错误。

有什么建议？

谢谢！

import socket
with open("test.txt", "r") as ins:
    for line in ins:
        print socket.gethostbyname(line.strip())
