Question

我需要重新配置apc网络管理卡，因为它们已使用错误的IP进行配置。我已经测试了通过Netmiko与它们的连接，并且发现'cisco_ios_telnet'设备类型有效，并且我可以输入命令并将其发送到设备。设备和更新的值在csv文件中列出。我的想法是将csv文件解析为行，然后使用NetMiko依次连接到每个文件，然后发出将更改其ip，掩码和网关的命令。

我想使用csv.DictReader（当然，如果合适的话）因为我不了解熊猫，而只是看到能起作用的东西，所以忽略了熊猫的台词。

我的csv文件（apc.csv）看起来像这样 ID，IP，目标，掩码，GW 1.1.1.1,2.2.2.2,255.0.0.0,2.2.2.1 1.1.1.2,2.2.2.3,255.0.0.0,2.2.2.1

*#!/usr/bin/env python
# -*- coding: utf-8 -*-
from __future__ import print_function, unicode_literals
import sys
import csv
import pandas as pd
import logging
from netmiko import ConnectHandler, Netmiko
from getpass import getpass

#df1 = pd.read_csv('apc.csv')

#df2 = df1.set_index("id", drop = False)

#print(df2[1:2])



with open('apc.csv') as csvfile:
    reader = csv.DictReader(csvfile,delimiter=" ")
    for row in reader:
        print(row['id'], row['ip'], row['target'], row['mask'], row['gw'])
        device = {
            'device_type': 'cisco_ios_telnet',
            'host': 'host',
            'username': 'user',
            'password': 'pass',
        }
net_connect = ConnectHandler(**device)
print("Connecting to device")
commands = ['tcpip -i[target] -s[mask] -g[gw]']

output = net_connect.send_command(commands)

net_connect.disconnect()*

我觉得我缺少了如何访问每个行和字段的值的概念
