PyPattyrn is a Python package providing ready-made base classes and metaclasses for common GoF design patterns like Singleton, Factory, Observer, and Adapter. It reduces the boilerplate needed to apply these patterns in Python projects.

Use cases

  • implement a singleton class in python without boilerplate
  • apply the observer pattern to my python project
  • create factory pattern base classes in python
  • learn how common design patterns are implemented in python
  • reuse design pattern boilerplate across python projects

When to choose

  • you need a quick reference implementation of a classic design pattern in Python
  • you are studying design patterns and want runnable Python examples

When to avoid

  • starting a new production project - the repo is explicitly unmaintained and its patterns are often unidiomatic in Python
  • you want idiomatic Python solutions, since most patterns are unnecessary in Python
