Python netmiko:如何使用'show version‘命令中的'Cisco IOS Software’打印出特定的行匹配？

Question

这是Cisco交换机show version命令的输出示例。

Switch#show version
Cisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version 15.0(2)SE, RELEASE SOFTWARE (fc1)
Technical Support: http://www.cisco.com/techsupport
Copyright (c) 1986-2012 by Cisco Systems, Inc.

目标:如果在'show Cisco IOS Software‘输出中发现字符串版本，我想打印整行。

为了更容易理解，我将show version输出放在变量shvar中

shvar = '''
Cisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version 15.0(2)SE, RELEASE SOFTWARE (fc1)
Technical Support: http://www.cisco.com/techsupport
Copyright (c) 1986-2012 by Cisco Systems, Inc.
'''

使用if进行搜索

>>> if 'Cisco IOS Software' in shvar:
...     print('Found ... print line')
... 
Found ... print line
>>> 

或者使用find进行搜索

>>> if shvar.find('Cisco IOS Software') > 0:
...     print('Found ... print line')
... 
Found ... print line
>>> 

问题是如何打印与'Cisco IOS Software‘匹配的行？

期望输出

Cisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version 15.0(2)SE, RELEASE SOFTWARE (fc1)

Answer 1

您可以只将字符串拆分成行。

for line in shvar.split("\n"):
   if 'Cisco IOS Software' in line:
      print(line)
