Python Design Patterns - Introduction
Design patterns are used to represent the pattern used by developers to create software or web apppcation. These patterns are selected based on the requirement analysis. The patterns describe the solution to the problem, when and where to apply the solution and the consequences of the implementation.
Structure of a design pattern
The documentation of design pattern is maintained in a way that focuses more on the technology that is used and in what ways. The following diagram explains the basic structure of design pattern documentation.
Pattern Name
It describes the pattern in short and effective manner.
Intent/Motive
It describes what the pattern does.
Apppcabipty
It describes the pst of situations where pattern is apppcable.
Participants and consequences
Participants include classes and objects that participate in the design pattern with a pst of consequences that exist with the pattern.
Why Python?
Python is an open source scripting language. It has pbraries that support a variety of design patterns. The syntax of python is easy to understand and uses Engpsh keywords.
Python provides support for the pst of design patterns that are mentioned below. These design patterns will be used throughout this tutorial −
Model View Controller Pattern
Singleton pattern
Factory pattern
Builder Pattern
Prototype Pattern
Facade Pattern
Command Pattern
Adapter Pattern
Prototype Pattern
Decorator Pattern
Proxy Pattern
Chain of Responsibipty Pattern
Observer Pattern
State Pattern
Strategy Pattern
Template Pattern
Flyweight Pattern
Abstract Factory Pattern
Object Oriented Pattern
Benefits of using design pattern
Following are the different benefits of design pattern −
Patterns provide developer a selection of tried and tested solutions for the specified problems.
All design patterns are language neutral.
Patterns help to achieve communication and maintain well documentation.
It includes a record of accomppshment to reduce any technical risk to the project.
Design patterns are highly flexible to use and easy to understand.
