Why Podium?

Podium has a few simple - yet powerful - goals in mind:

• Reduce the need to know how to interact with data objects (e.g. DataFrame APIs)
• Simplify the ability to express expectations of your data objects

Inspiration

The name of this package came about in the following manner:

• This package implements narwhals - a group of narwhals is considered a pod
• This package is an opinionated workflow orchestrator, so a podium seems a fitting environment to share these opinions
