Pandera is a data validation library for tabular data that uses DataFrameSchema and SeriesSchema to enforce data types and run checks. The 0.32.0 release introduces a Narwhals-powered unified backend that validates data across multiple dataframe libraries, including Pandas, Polars, PySpark, Dask, Modin, and GeoPandas. It integrates with the broader data ecosystem (e.g., FastAPI, Mypy, Pydantic) and provides features such as lazy validation, error reporting, parsers, schema inference, and IO/serialization support.

Excerpts where Pandera appeared in the AI's answer

Pandera — Excellent if your pipeline operates strictly on Pandas or Polars DataFrames and you want to define schemas inline using Python data classes or function decorators
