Is a class a new data type?

You can build object-oriented applications by creating classes. A class is a data type that restricts access to its data to a set of procedures . These procedures control the ways that an instance of a class (an object) is initialized, accessed, and finally deleted when it is no longer needed.

As nouns the difference between category and class is that category is a group, often named or numbered, to which items are assigned based on similarity or defined criteria while class is (countable) a group, collection, category or set sharing characteristics or attributes.

Basically a type is class that inherits from object . In Python3, all classes inherit from object , so they are the same thing.

Class is a blueprint or template from which objects are created. Object is an instance of a class .
