python attr

Python attr is a library that provides a way to define classes with attributes in a concise and easy-to-read syntax. It allows you to define classes with attributes that have default values, validators, converters, and more. Attr makes it easy to create classes that are flexible and easy to use, and it helps you avoid boilerplate code. It is especially useful when dealing with data classes, where you need to define classes that hold data but don't have any behavior. With attr, you can define such classes easily and quickly.
