Sometimes you just want to switch off your computer and read from a book. So, I’ve revisited and rewritten all of the 23 GoF design patterns and compiled them into a book titled Design Patterns In Python. ASIN B08XLJ8Z2J

Book provides FREE access to online instructional videos.

Design patterns will give you a useful and common vocabulary for when designing, documenting, analysing restructuring new and existing software development projects now and into the future.

Sometimes you need an object in an application where there is only one instance.

You don’t want there to be many versions, for example, you have a game with a score and you want to adjust it. You may have accidentally created several instances of the class holding the score…


The Prototype design pattern is good for when creating new objects requires more resources than you want to use or have available. You can save resources by just creating a copy of any existing object that is already in memory.

E.g., A file you’ve downloaded from a server may be…


The Builder Pattern is a creational pattern whose intent is to separate the construction of a complex object from its representation so that you can use the same construction process to create different representations.

The Builder Pattern tries to solve,

  • How can a class create different representations of a complex…

The Abstract Factory Pattern adds an abstraction layer over multiple other creational pattern implementations.

To begin with, in simple terms, think if it as a Factory that can return Factories. Although you will find examples of it also begin used to return Builder, Prototypes, Singletons or other design pattern implementations.

Terminology


When developing code, you may instantiate objects directly in methods or in classes. While this is quite normal, you may want to add an extra abstraction between the creation of the object and where it is used in your project.

You can use the Factory pattern to add that extra…
