Object Oriented Programming

A blueprint which can be used to create an object. Contains methods and variables.

• Constructors

• Classes

• Objects

• Properties

A child class gains methods and properties from the parent class.

• Inheritance

• Objects

• Attributes

• Methods

A special kind of attribute. Has a "getter" (__get__), a "setter" (__set__), and "delete" (__delete__) method.

• Objects

• Properties

• Methods

• Attributes

Created when a new object is instantiated and isn't available to other objects. They are accessible by methods but declared outside methods.

• Instance Variable

• Methods

• Inheritance

• Classes

Used in objects to hold data. They are similar, but different, from a variable.

• Class Variables

• Objects

• Attributes

• Constructors

A special method that Python uses to instantiate an instance or object. They assign values to instance variable, and are always named "__init__()"

• Instances

• Attributes

• Constructors

• Methods

Created inside a class but outside any methods. Can be changed by calling the class variable, but changes may impact all places that the variable is used.

• Methods

• Constructors

• Instance Variables

• Class Variables

Functions available only to objects of that type. Defined within the class and perform some actions that are helpful to that specific type of object.

• Classes

• Inheritance

• Constructors

• Methods

An object recreated by following the "blueprint" defined by the class. It "inherits" the methods and variables from the class it was created from, however the data may be different.

• Properties

• Instances
