2. Python syntax and semantics - Wikipedia

   en.wikipedia.org/wiki/Python_syntax_and_semantics

   Object system. In Python, everything is an object, even classes. Classes, as objects, have a class, which is known as their metaclass. Python also supports multiple inheritance and mixins. The language supports extensive introspection of types and classes. Types can be read and compared—types are instances of type. The attributes of an object ...

3. Class (computer programming) - Wikipedia

   en.wikipedia.org/wiki/Class_(computer_programming)

   In class-based programming, objects are created as instances of classes by subroutines called constructors, and destroyed by destructors. An object is an instance of a class as it can access to all data types (primitive as well as non primitive), and methods etc., of a class. Therefore, objects may be called a class instances or class objects.

4. Python (programming language) - Wikipedia

   en.wikipedia.org/wiki/Python_(programming_language)

   Design philosophy and features. Python is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of their features support functional programming and aspect-oriented programming (including metaprogramming [69] and metaobjects ). [70]

5. Object-oriented programming - Wikipedia

   en.wikipedia.org/wiki/Object-oriented_programming

   Objects are instances of a class. Object-oriented programming ( OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties ), and code in the form of procedures (often known as methods ). In OOP, computer programs are designed by making ...

6. Constructor (object-oriented programming) - Wikipedia

   en.wikipedia.org/wiki/Constructor_(object...

   v. t. e. In class-based, object-oriented programming, a constructor (abbreviation: ctor) is a special type of function called to create an object. It prepares the new object for use, often accepting arguments that the constructor uses to set required member variables .

7. Factory method pattern - Wikipedia

   en.wikipedia.org/wiki/Factory_method_pattern

   In object oriented programming, the factory method pattern is a creational pattern that uses factory methods to deal with the problem of creating objects without having to specify their exact class. Rather than by calling a constructor, this is done by calling a factory method to create an object. Factory methods can either be specified in an ...

8. History of Python - Wikipedia

   en.wikipedia.org/wiki/History_of_Python

   Python 2.2 was released in December 2001; a major innovation was the unification of Python's types (types written in C) and classes (types written in Python) into one hierarchy. This single unification made Python's object model purely and consistently object oriented. Also added were generators which were inspired by Icon.

9. Class-based programming - Wikipedia

   en.wikipedia.org/wiki/Class-based_programming

   Class-based programming. Class-based programming, or more commonly class-orientation, is a style of object-oriented programming (OOP) in which inheritance occurs via defining classes of objects, instead of inheritance occurring via the objects alone (compare prototype-based programming ). The most popular and developed model of OOP is a class ...
