The "Criteria Pattern" is a Python 🐍 package that simplifies and standardizes criteria based filtering 🤏🏻, validation and selection. This package provides a set of prebuilt 👷🏻 objects and utilities that you can drop into your existing projects and not have to implement yourself.

These utilities 🛠️ are useful when you need complex filtering logic. It also enforces 👮🏻 best practices so all your filtering processes follow a uniform standard.

Easy to install and integrate, this is a must have for any Python developer looking to simplify their workflow, enforce design patterns and use the full power of modern ORMs and SQL 🗄️ in their projects 🚀.
