Python批量备份交换机配置+自动巡检
自动巡检功能考虑到不同设备回显有所不同，需要大量正则匹配，暂时没时间搞这些，所以索性将命令回显全部显示，没做进一步的回显提取。
以下是程序运行示例：
#自动备份配置：
备份完成后，将配置保存于程序目录下的conf_bak文件夹下，如图所示：
#自动巡检交换机设备：
使用前需创建excel文档，写入设备登录信息，格式如下：
本人编码能力一般，勿喷，源码：

# 获取最大行数
row = sh.max_row
# 获取最大列数
column = sh.max_column
data = []
# 获取表头写入列表中方便调用
for data_1 in range(1, column+1):
get_sheet_header = sh.cell(row=1, column=data_1).value
sheet_header.append(get_sheet_header)
# 第一行为表头， 此处 row +1 是pyton循环时不读取最后一个数

# 存储一行信息
sheet_data_1 = dict()
# 逐行读取表中的数据
