Is there any simple way in matplotlib, or in any other python library, to
make a simple Venn diagram, I want to show three events and their

You can use Sage (http://www.sagemath.org or http://sagenb.org)
(scroll down to see the picture; email me off-list if you'd like help in setting up an account or installing Sage; you can use Sage as a python library).
Even if you don't use Sage and something like the interactive Venn diagram listed in the URL gives you relevant code for creating such a thing in matplotlib.
Sage uses matplotlib in the background to actually draw the Venn diagram.
