-DESCRIPTION = "Powerful data structures for data analysis, time series, and statistics"
-LONG_DESCRIPTION = """
-**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.
-
-pandas is well suited for many different kinds of data:
-
-  - Tabular data with heterogeneously-typed columns, as in an SQL table or
-    Excel spreadsheet
-  - Ordered and unordered (not necessarily fixed-frequency) time series data.
-  - Arbitrary matrix data (homogeneously typed or heterogeneous) with row and
-    column labels
-  - Any other form of observational / statistical data sets. The data actually
-    need not be labeled at all to be placed into a pandas data structure
-
-The two primary data structures of pandas, Series (1-dimensional) and DataFrame
-(2-dimensional), handle the vast majority of typical use cases in finance,
-statistics, social science, and many areas of engineering. For R users,
-DataFrame provides everything that R's ``data.frame`` provides and much
-more. pandas is built on top of `NumPy <https://www.numpy.org>`__ and is
-intended to integrate well within a scientific computing environment with many
-other 3rd party libraries.
-
-Here are just a few of the things that pandas does well:
-
-  - Easy handling of **missing data** (represented as NaN) in floating point as
-    well as non-floating point data
-  - Size mutability: columns can be **inserted and deleted** from DataFrame and
-    higher dimensional objects
-  - Automatic and explicit **data alignment**: objects can be explicitly
-    aligned to a set of labels, or the user can simply ignore the labels and
-    let `Series`, `DataFrame`, etc. automatically align the data for you in
-    computations
-  - Powerful, flexible **group by** functionality to perform
-    split-apply-combine operations on data sets, for both aggregating and
-    transforming data
-  - Make it **easy to convert** ragged, differently-indexed data in other
-    Python and NumPy data structures into DataFrame objects
-  - Intelligent label-based **slicing**, **fancy indexing**, and **subsetting**
-    of large data sets
-  - Intuitive **merging** and **joining** data sets
-  - Flexible **reshaping** and pivoting of data sets
-  - **Hierarchical** labeling of axes (possible to have multiple labels per
-    tick)
-  - Robust IO tools for loading data from **flat files** (CSV and delimited),
-    Excel files, databases, and saving / loading data from the ultrafast **HDF5
-    format**
-  - **Time series**-specific functionality: date range generation and frequency
-    conversion, moving window statistics, date shifting and lagging.
-
-Many of these principles are here to address the shortcomings frequently
-experienced using other languages / scientific research environments. For data
-scientists, working with data is typically divided into multiple stages:
-munging and cleaning data, analyzing / modeling it, then organizing the results
-of the analysis into a form suitable for plotting or tabular display. pandas is
-the ideal tool for all of these tasks.
