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 for doing practical, real world data analysis in Python. Additionally, it has the broader goal of becoming the most powerful and flexible open source data analysis / manipulation tool available in any language.
pandas is well suited for many different kinds of data:
Tabular data, as in an SQL table or Excel spreadsheet
Ordered and unordered (not necessarily fixed-frequency) time series data
Matrix data, potentially with row and column labels
