How to caputre an output of a CLI - vel9194 - Aug-07-2017
I need to capture an output of a CLI "show lic ?" in a variable or in buffer.
How to do it in python. I was using tcl where it has "receive_buffer" to capture it, not sure how to do it on python.
Please find the output below
Switch#show lic ?

Look at the Subprocess module.

You can capture and store the output in a variable by pointing sys.stdout to the variable and executing your command.
eg->
o_variable = StringIO() # variable to store stdout stream sys.stdout = o_variable # pointing stdout to variable #Execute your commands sys.stdout = sys.__stdout__ #restore std out output = o_variable.getvalue() print(output)
