2. Python (programming language) - Wikipedia

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

   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 [70] and metaobjects). [71] Many other paradigms are supported via extensions, including design by ...

3. Python syntax and semantics - Wikipedia

   en.wikipedia.org/wiki/Python_syntax_and_semantics

   Python syntax and semantics. A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java ...

4. Class (computer programming) - Wikipedia

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

   A class defines an implementation of an interface, and instantiating the class results in an object that exposes the implementation via the interface. [3] In the terms of type theory, a class is an implementation‍—‌a concrete data structure and collection of subroutines‍—‌while a type is an interface. Different (concrete) classes ...

5. Zen of Python - Wikipedia

   en.wikipedia.org/wiki/Zen_of_Python

   Zen of Python. The Zen of Python output in a terminal. The Zen of Python is a collection of 19 "guiding principles" for writing computer programs that influence the design of the Python programming language. [1] Python code that aligns with these principles is often referred to as "Pythonic". [2]

6. 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).

7. Factory method pattern - Wikipedia

   en.wikipedia.org/wiki/Factory_method_pattern

   Factory method pattern. In object-oriented programming, the factory method pattern is a design pattern that uses factory methods to deal with the problem of creating objects without having to specify their exact classes. Rather than by calling a constructor, this is accomplished by invoking a factory method to create an object.

8. Inheritance (object-oriented programming) - Wikipedia

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

   In object-oriented programming, inheritance is the mechanism of basing an object or class upon another object (prototype-based inheritance) or class (class-based inheritance), retaining similar implementation. Also defined as deriving new classes (sub classes) from existing ones such as super class or base class and then forming them into a ...

9. Constructor (object-oriented programming) - Wikipedia

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

   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. A constructor resembles an instance method, but it differs from a method in that it ...
