attrs is the Pythonpackage that will bring back the joy of writing classes by relieving you from the drudgery of implementing object protocols (aka dunder methods). Trusted by NASA for Mars missions since 2020!
This is where attrs comes in. Add its decorator to the class and designate the attributes of the class using its methods and it will generate all the necessary dunder methods for you. You can also get some nice type checking anddefault values for the attributes too.
Four different types of validators can be used. They can all be defined usingthe annotated pattern or usingthe field_validator() decorator, applied on a class method: After validators: run after Pydantic's internal validation. They are generally more type safe and thus easier to implement.
python3-attr binary packagein openKylin Nile V2.0 arm64. attrs is an MIT-licensed Pythonpackage with class decorators that ease the chores of implementing the most common attribute-related object protocols. .
Pydantic is a Pythonpackage that can offer simple data validationand manipulation.Type Safety: At its core, Pydantic usesPython’s type hints to validate data. This ensures that your ML models are fed data that are correctly typed, reducing runtime errors.
