Type annotations for pandas

pandas-stubs: Public type stubs for pandas

What is it?

These are public type stubs for pandas, following the convention of providing stubs in a separate package, as specified in PEP 561. The stubs cover the most typical use cases of pandas. In general, these stubs are narrower than what is possibly allowed by pandas, but follow a convention of suggesting best recommended practices for using pandas.

The stubs are likely incomplete in terms of covering the published API of pandas.

The stubs are tested with mypy and pyright and are currently shipped with the Visual Studio Code extension pylance.

Version Numbering Convention

The version number x.y.z.yymmdd corresponds to a test done with pandas version x.y.z, with the stubs released on the date mm/yy/dd. It is anticipated that the stubs will be released more frequently than pandas as the stubs are expected to evolve due to more public visibility.

Documentation

Documentation is a work-in-progress.

Background

These stubs are the result of a strategic effort lead by the core pandas team to integrate Microsoft type stub repository together with the VirtusLabs pandas_stubs repository.

These stubs were initially forked from the Microsoft project https://github.com/microsoft/python-type-stubs as of this commit.

We are indebted to Microsoft and that project for the initial set of public type stubs. We are also grateful for the original pandas-stubs project at https://github.com/VirtusLab/pandas-stubs that created the framework for testing the stubs.
