接上篇：
这次我写了一个稍微复杂的textfsm模板（模板里有filldown、required、list），利用net_inspect提取华为USG防火墙地址对象信息，只是扩展net_inspect的实际应用场景，希望可以激发大家对net_inspect和textfsm的兴趣，再次感谢 @Elin 大神的付出！

for device in net.cluster.devices:

print(info.hostname)
with device.search_cmd(&#39;display ip address-set type object&#39;) as cmd:
df = cmd.parse_result
aaa = pd.DataFrame(df)
aaa.to_csv(&#34;objects.csv&#34;, index=False)
print(&#34;请检查生成的csv文件！&#34;)
aaa.to_excel(&#39;objects.xlsx&#39;)
print(&#34;请用WPS或Office打开生成的xlsx文件！&#34;)请注意：net-inspect作者还在陆续更新版本，如果新版本碰到类似下面的报错，按照提示修改代码参数即可：
net.run(input_path=r&#39;D:\Py_exec\logs&#39;)
NetInspect.run: `path`参数已废弃, 请使用`input_path`参数代替.执行代码后的输出
