Show HN: Pandera – An open source data testing framework for data science and ML (pandera.readthedocs.io)

Hi HN,

I'm excited to share Pandera, an open source framework for data testing, built for data scientists and ML engineers: https://www.union.ai/pandera

I’ve been working with data and building models for a decade, and one of the biggest pain points for me is working with low-quality data. I got burned by incorrect data types and unexpected values so many times that I built a Pandera to help you safeguard your pipelines from silent data bugs.

You can create schemas for your dataframe-like objects, which can be validated at run-time, in your unit tests via property-based testing, or in your type-linting hooks via mypy.

Give it a try here: https://pandera.readthedocs.io/en/stable/try_pandera.html
