Everything About Python - What is an Object?
In object-oriented programming, an object is an instance that has the attributes (data) and methods (functions) defined by a class, which serves as a program's blueprint.
In simple terms, an object is created based on the blueprint provided by a class.
Python follows the philosophy of "Everything is an object".
Numbers, strings, functions, classes, and almost everything used in Python are considered objects.
As a result, variables, functions, classes, and all elements have their own attributes and methods as objects.
Reviewing the Components of an Object
-
Attributes: These represent the characteristics or state of an object. For example, aDogobject might have attributes such asname,age, andbreed. -
Methods: These define the actions or behaviors that an object can perform. For instance, aDogobject might include methods such asbark()orrun()to represent those behaviors.
In the next lesson, we will explore concrete examples of classes and objects (instances).
