Step 1: Environment Setup

In this tutorial, we will setup the python 2.7 environment.

Before Start

You should have python 2.7 installed. Generally, if you are using CentOS 7.2, Ubuntu LTS, python 2.7 is installed by default.

Using the following command to check the installation:

~$ python --version
Python 2.7.12

~$ pip --version
pip 9.0.1 from /home/cesbd/.local/lib/python2.7/site-packages (python 2.7)

~$ ipython --version

IPython Playground

IPython is a good start to play with python expressions and directives:

~$ ipython
Python 2.7.12 (default, Nov 20 2017, 18:23:56)
Type "copyright", "credits" or "license" for more information.
