【问题描述】：

我正在尝试使用 IP 地址列表创建 nslookup。我正在 Windows 7 机器上执行nslookup。我得到的错误是，当我运行nslookup 时，我每次都将变量result 恢复为零。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)

【解决方案1】：

os.system 不返回您运行的命令的输出；它会打印它。

要运行命令并获取其输出，请改用os.popen(...).read()：

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