pandas: powerful Python data analysis toolkit
Latest Release Package Status License Build Status Coverage Downloads Gitter
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 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 towards this goal.
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
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, moving window linear regressions, date shifting and lagging, etc.
Where to get it
The source code is currently hosted on GitHub at: https://github.com/pandas-dev/pandas
Binary installers for the latest released version are available at the Python package index and on conda.
# conda conda install pandas
# or PyPI pip install pandas
See the full installation instructions for recommended and optional dependencies.
Installation from sources
To install pandas from source you need Cython in addition to the normal dependencies above. Cython can be installed from pypi:
pip install cython
pandas directory (same one where you found this file after
cloning the git repo), execute:
python setup.py install
or for installing in development mode:
python setup.py develop
Alternatively, you can use
pip if you want all the dependencies pulled
in automatically (the
-e option is for installing it in development
pip install -e .
See the full instructions for installing from source.
The official documentation is hosted on PyData.org: https://pandas.pydata.org/pandas-docs/stable
pandas started at AQR (a quantitative hedge fund) in 2008 and
has been under active development since then.
Discussion and Development
Most development discussion is taking place on github in this repo. Further, the pandas-dev mailing list can also be used for specialized discussions or design issues, and a Gitter channel is available for quick development related questions.
All contributions, bug reports, bug fixes, documentation improvements, enhancements and ideas are welcome.
A detailed overview on how to contribute can be found in the contributing guide. There is also an [overview](.github/CONTRIBUTING.md) on GitHub.
If you are simply looking to start working with the pandas codebase, navigate to the GitHub "issues" tab and start looking through interesting issues. There are a number of issues listed under Docs and good first issue where you could start out.
You can also triage issues which may include reproducing bug reports, or asking for vital information such as version numbers or reproduction instructions. If you would like to start triaging issues, one easy way to get started is to subscribe to pandas on CodeTriage.
Or maybe through using pandas you have an idea of your own or are looking for something in the documentation and thinking ‘this can be improved’...you can do something about it!
