Thank you very much Robin for your help.

I have to execute some action if the server is CentOS.

The server_description variable may or may not store CentOS key word among few other words. So I was thinking, if I could execute
"CentOS in server_description which would return either "True" or "False". If it is True, the python would perform some action. I have been advised to store the True or False value in another variable.

My problem is I am unable to store True or False in other variable, say, my_Check.

If I could do that, probably I could use the following -
Code:
if my_check == "True":
    do_something
else:
     do_otherthing

Could you please advice, how I can store a command's output, here, "CentOS in server_description in a variable (or any other python level command later) and use the value of the variable whenever required.
e.g.
Code:
server_description = "This is xyz abc of mno CentOS"
my_Check = "CentOS" in server_description
if my_Check == "True":
    print("This is CentOS")
else:
    print("This is NOT CentOS")

The output I am getting is "This is NOT CentOS"
CentOS 7.4 is OS version and Python 3.4.5
I could do it using shell, but I have been asked to use Python only, as the action to be performed based on the condition, if True or False, is already written in Python.
Please don't consider my objective is to print either CentOS or NOT CentOS, rather some other successfully written python code that I will be pasting in if or else section.

While testing, I found this, but not sure why it is not working...
Code:
>>> server_description = "CentOS"
>>> my_Check = "centos" in server_description
>>> my_Check
False
>>> my_Check = "CentOS" in server_description
>>> my_Check
True

isympy

isympy(1)																 isympy(1)

NAME

       isympy - interactive shell for SymPy

SYNOPSIS

       isympy [-c | --console]
       isympy [ {-h | --help} | {-v | --version} ]

DESCRIPTION

       isympy  is  a  Python shell for SymPy. It is just a normal python shell (ipython shell if you have the ipython package installed) that exe-
       cutes the following commands so that you don't have to:

       >>> from __future__ import division
       >>> from sympy import *
       >>> x, y, z = symbols("xyz")
       >>> k, m, n = symbols("kmn", integer=True)

       So starting isympy is equivalent to starting python (or ipython) and executing the above commands by hand. It  is  intended  for  easy  and
       quick  experimentation  with  SymPy. For more complicated programs, it is recommended to write a script and import things explicitly (using
       the "from sympy import sin, log, Symbol, ..." idiom).

OPTIONS

       -c shell, --console=shell
	      Use the specified shell (python or ipython) as console backend instead of the default one (ipython if present or python otherwise).

	      Example: isympy -c python

FILES

       ${HOME}/.sympy-history
	      Saves the history of commands when using the python shell as backend.

BUGS

       The upstreams BTS can be found at <http://code.google.com/p/sympy/issues/list> Please report all bugs that you find  in	there,	this  will
       help improve the overall quality of SymPy.
