In Python, an object is a fundamental concept in object-oriented programming (OOP). An object is an instance of a class, and a class is a blueprint that defines the attributes (data) and methods (functions) that the objects of that class will have. Objects encapsulate data and behavior ...
An object has a ‘reference count’ that is increased or decreased when a pointer to the object is copied or deleted; when the reference count reaches zero there are no references to the object left and it can be removed from the heap. An object has a ‘type’ that determines what it ...
Python is also an object-oriented language, in contrast to functional programming languages, such as C. Object-oriented languages design software around objects, which can be real-world entities, such as cars, or abstract concepts, such as numbers. Objects are instances of a class (for example...
