Real Python - Using Data Classes in Python

https://realpython.com/courses/python-data-classes/

One new and exciting feature that came out in Python 3.7 was the data class. A data class is a class typically containing mainly data, although there aren’t really any restrictions.

With data classes, you don’t have to write boilerplate code to get proper initialization, representation, and comparisons for your objects.

In this course, you’ll learn how to:

Define your own data classes
Add default values to the fields in your data class
Customize the ordering of data class objects
Work with immutable data classes

For example, there are multiple ways to read a file in Python, including the rarely used mmap module.
