## Python library for Apache Arrow

[![pypi](https://img.shields.io/pypi/v/pyarrow.svg)](https://pypi.org/project/pyarrow/) [![conda-forge](https://anaconda.org/conda-forge/pyarrow/badges/version.svg)](https://anaconda.org/conda-forge/pyarrow)

This library provides a Python API for functionality provided by the Arrow C++
libraries, along with tools for Arrow integration and interoperability...

## AI interpretation — verify before relying

pyarrow is a Python library providing access to Apache Arrow's C++ data structures and computation engine, enabling efficient columnar data processing and interoperability with pandas, NumPy, and other Python ecosystem tools.

Verdict: pyarrow is a mature, actively maintained top-100 PyPI package with zero known vulnerabilities and permissive Apache-2.0 licensing. Medium install friction is typical for compiled libraries and well-mitigated by pre-built wheels across major platforms. Suitable for production data processing pipelines.
