pandas is a Python package that provides fast, flexible, and expressive data
structures designed to make working with structured (tabular, multidimensional,
potentially heterogeneous) and time series 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. It is
already well on its way toward this goal.
Shapely is a BSD-licensed Python package for manipulation and analysis of planar
geometric objects. It is based on the widely deployed
GEOS (the engine of PostGIS) and
