在 Windows 7 Cmd 提示符中获取 nslookup 结果

Question

我正在尝试 nslookup 使用 IP 地址列表。我正在 Windows 7 机器上执行 nslookup。我得到的错误是，当我运行和 nslookup 时，我每次都将变量 result 返回为零。我如何获得

   Server: server.address.com
   Address: 10.45.66.77

   Server: server.address.com
   Address: 108.36.85.35

作为我的结果而不是 0？

#!/usr/bin/env python

#purpose of script: To conduct an nslookup on a list of IP addresses

import os, csv

#get list of IP's from file
inFile='filelocation/Book1.txt'
ipList = []
with open(inFile, 'rb') as fi:
    for line in fi: 
        line = line.replace(',', '')#remove commas and \n from list
        line = line.replace('\r', '')
        line = line.replace('\n', '')
        ipList.append(line)# create list of IP addresses to lookup

#output results
outFile='filelocation/outFile.txt'
fo = open(outFile, 'w')
for e in ipList:
    result = str(os.system('nslookup ' + e))#send nsLookup command to cmd prompt. Result = 0 everytime
    fo.write(result)

Answer 1

os.system 不会 return 您运行命令的输出；它改为打印它。

要运行一个命令并得到它的输出，请改用os.popen(...).read()：

result = os.popen('nslookup ' + e).read()
