*What is it:*

*pandas* is a Python package providing fast, flexible, and expressive data
structures designed to make working with “relational” or “labeled” data both
easy and intuitive. It aims to be the fundamental high-level building block
doing practical, real world data analysis in Python. Additionally, it has
broader goal of becoming the most powerful and flexible open source data
analysis / manipulation tool available in any language.
