How to caputre an output of a CLI

[hbknjr]

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)
