The original title is: "Simple Factory, Factory Method, Abstract Factory — Which One Do You Need?"

Short summary

A tutorial comparing three factory design patterns in Python, starting from a naive approach that violates SRP and OCP. It progresses from Simple Factory (centralizing creation logic) to Factory Method (each subclass creates its own objects) to Abstract Factory. Code examples illustrate how each pattern addresses different coupling and extensibility problems.

• •Simple Factory centralizes object creation but still violates OCP
• •Factory Method eliminates conditionals by letting each subclass create its own objects
• •Abstract Factory handles families of related objects across multiple product types
