Though, any IDE will also do the job, just by calling a print() statement on the DataFrame object. We'll be using the Jupyter Notebook since it offers a nice visual representation of DataFrames. In this article we will go through the most common ways of creating a DataFrame and methods to change their structure. Heterogenous means that not all "rows" need to be of equal size. Series are essentially one-dimensional labeled arrays of any type of data, while DataFrames are two-dimensional, with potentially heterogenous data types, labeled arrays of any type of data. The two main data structures in Pandas are Series and DataFrame. It is designed for efficient and intuitive handling and processing of structured data. 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!įeel free to ask questions on the mailing list or on Slack.Īs contributors and maintainers to this project, you are expected to abide by pandas' code of conduct.Pandas is an open-source Python library for data analysis. If you would like to start triaging issues, one easy way to get started is to subscribe to pandas on CodeTriage. You can also triage issues which may include reproducing bug reports, or asking for vital information such as version numbers or reproduction instructions. There are a number of issues listed under Docs and good first issue where you could start out. If you are simply looking to start working with the pandas codebase, navigate to the GitHub "issues" tab and start looking through interesting issues. Contributing to pandasĪll contributions, bug reports, bug fixes, documentation improvements, enhancements, and ideas are welcome.Ī detailed overview on how to contribute can be found in the contributing guide. Further, the pandas-dev mailing list can also be used for specialized discussions or design issues, and a Slack channel is available for quick development related questions. Most development discussions take place on GitHub in this repo. Getting Helpįor usage questions, the best place to go to is StackOverflow.įurther, general questions and discussions can also take place on the pydata mailing list. Has been under active development since then. Work on pandas started at AQR (a quantitative hedge fund) in 2008 and The official documentation is hosted on : Background See the full instructions for installing from source. Or for installing in development mode: python -m pip install -e. In the pandas directory (same one where you found this file afterĬloning the git repo), execute: python setup.py install Cython can be installed from PyPI: pip install cython To install pandas from source you need Cython in addition to the normalĭependencies above. See the full installation instructions for minimum supported versions of required, recommended and optional dependencies. pytz - Brings the Olson tz database into Python which allows accurate and cross platform timezone calculations.python-dateutil - Provides powerful extensions to the standard datetime module.
