Python virtualenv what why ?

virtualenv i.e. Virtual Environment, I never thought such this thing exists before working on
python, but it exists and it great to avoid conflicts and maintain a separate copy of Python and
libs utilized in your project.
Installation –
Simple – sudo pip installvirtualenv

This command helps if you are taking pull of existing project from code repo and wanted to
use it new env, activate your new env by running commands – “virtualenv env” and then run following
sudo pip install virtualenv --upgrade
