   @Bananach: the @dataclass generates roughly the same __init__ method, with a quantity_on_hand keyword argument with default value. When you create an instance, it'll set the quantity_on_hand instance attribute, always. So my first, non-dataclass example uses the same pattern to echo what the dataclass generated code will do. –

   What is a dataclass in Python?

   • DataClasses provides a decorator and functions for automatically adding generated special methods such as __init__ () , __repr__ () and __eq__ () to user-defined classes. DataClasses are like normal classes in Python, but they have some basic functions like instantiation, comparing, and printing the classes already implemented.

   How are dataclasses implemented in Python?

   • The DataClasses are implemented by using decorators with classes. Attributes are declared using Type Hints in Python which is essentially, specifying data type for variables in python. Output: The two noticeable points in above code. Without a __init__ () constructor, the class accepted values and assigned it to appropriate variables.

   Why should I use dataclasses?

   • Every time you create a class that mostly consists of attributes, you make a data class. What the dataclasses module does is to make it easier to create data classes. It takes care of a lot of boilerplate for you. This is especially useful when your data class must be hashable; because this requires a __hash__ method as well as an __eq__ method.
