Donut chart with python matplotlib

Recently I had to sketch a donut chart for one of my projects using python matplotlib. When I looked into the example provided in matplotlib site for donut chart, the code was not very clear and obvious to me. So I was thinking of other ways to sketch a donut chart. Then I realized, donut is a pie with a big hole at the center, so why not draw a pie chart and impose white circle on top of it to make it look like a donut. Voila!!

This is the python code from Github. I used the example pie chart code from matplotlib site and drew a white circle at the center of the pie.
