python - Python netmiko：如何在“show version”命令中打印出与“Cisco IOS Software”匹配的特定行？

Question

这是 Cisco Switch show version 命令的示例输出。

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“显示版本”输出中找到字符串Cisco IOS Software，我想打印整行。

为了更容易理解，让我把show version输出放在变量中shvar

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.
'''

搜索if

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

或搜索find

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

问题是如何打印与“Cisco IOS 软件”匹配的行？

期望的输出

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

Answer 1

你可以把字符串分成几行。

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