Yes, PyCon India 2014 is happening in Bangalore. Interesting topics are on there for you on day 2. Workshops are also been conducted as a part of day 1 program. I have attended the one in year 2012 and some of the topics were really good to know and worth attending. The topics which focus on large data processing, performance, high scalable application in python, complex data structure would be worth to attend.

So as I see the topics on the PyCon India Website, if not changed, my favorite topic would be,
Python + Spark: Lightning Fast Cluster Computing
Django Design Patterns
New Scientific Plotting in Python
Faster data processing in Python
