 Virtual Environments are used to isolate python versions and package dependencies for each specific project.
+We'll begin by creating specific users for python:
+<Code:bash>
+> adduser py2
+...
+<password>
+...
+> adduser py3
+...
+<password>
+...
+# To act as py2:
+> su py2
+</Code>
 We'll install ''virtualenv'' for User only in order to allow coexistence of Python2 and Python3. As the virtualenv binary will bear the same name for 2 & 3, we'll move them on the go:
