I am masters students in data engineering and interested in contributing to scipy. I need some directions to how to start with it.  I know python and have worked on projects including data mining , web mining and  web crawlers etc.  I want to contribute to scipy by improving datasource and its integrations like handling malformed URLs, proxy settings , other file extensions support.
