Dataclasses are a key feature of the Python programming language, enabling developers to define data structures in a clear and concise manner. These classes automatically generate standard methods such as __init__, __repr__, and __eq__, simplifying the handling of structured data.
One of the primary advantages of dataclasses is the ability to assign default scalar values to fields; for example, you can define the batch_size parameter with a default value of 500: batch_size: int = 500. This simple and intuitive defaulting mechanism makes large-scale data processing code, particularly in the fields of artificial intelligence and machine learning, easy to configure and scalable.
