Question

我在python 3中编写了一些代码来执行这些操作：

读取主机文件并执行ping每个主机
写入无法访问的IP主机文件

import subprocess
fp = open('ip_host.txt') # open file ip host
text_file = open("result_ping.txt", "w") # open file result ping host 

for ip in fp.readlines():
    response = subprocess.Popen(["ping.exe",ip])
response.wait()

result = []
if response.poll():
    res_down = (ip + " - is down")
else:
    res_up = (ip + " - is up")

    result.append(res_down)
text_file.write(result)

fp.close() 
text_file.close()

但执行代码时显示错误：

    result.append(res_down)
NameError: name 'res_down' is not defined

如何解决？

总的来说，您可以大大清理代码。

另外，我认为您应该等待每个IP ，而不是等待文件中的最后一行。

import subprocess
with open('ip_host.txt') as fp, open("result_ping.txt", "w") as text_file:
    for ip in fp:
        response = subprocess.Popen(["ping.exe",ip])
        response.wait()

        if response.poll():
            text_file.write(ip + " - is down")
        else:
            res_up = (ip + " - is up")
        text_file.write("\n")

写入结果时错误ping主机到文件
