Learn Data Classes In python.
In this video, we look at dataclasses in Python.
Data classes is a module that includes a decorator and procedures for adding generated special methods to user-defined classes, such as __init__() and __repr__().
Using dataclasses allows you create classes with less boiler plate code. It also allows you to write readable and maintainable code. In this video, we look at the concepts involved when using dataclasses using a simple example.
