Everything in Python is an object, or so the saying goes. If you want to create your own custom objects, with their own properties and methods, you use Python’s
class object to make that happen. But creating classes in Python sometimes means writing loads of repetitive, boilerplate code to set up the class instance from the parameters passed to it or to create common functions like comparison operators.
Dataclasses, introduced in Python 3.7 (and backported to Python 3.6), provide a handy way to make classes less verbose. Many of the common things you do in a class, like instantiating properties from the arguments passed to the class, can be reduced to a few basic instructions.
