I've been working on a Python package that I think many of you might find useful, especially if you’ve ever found yourself re-implementing the same architectural building blocks across projects.
What is pattern_kit?
pattern_kit is a lightweight Python library that provides clean, idiomatic implementations of software design patterns.
Think of it as a toolkit that helps you write better-structured, more maintainable Python code without reinventing the wheel.
Available on PyPI: pip install pattern_kit

Why I Built It
Across different projects, I kept reimplementing the same design patterns such as Singleton, EventEmitter, ServiceLocator, etc...
It got repetitive. So I packaged them up into one reusable, testable, well-documented library. Bonus: they're all type-hinted and async-safe where it makes sense.
What You'll Find in pattern_kit
- Typed and tested implementations
- Async support where applicable
- Zero dependency
- Clear docs with usage examples
I'd Love Your Feedback
This is still a growing project. If you:
- Try it and like it, let me know!
- Have suggestions or pattern ideas, open an issue or PR
- Spot anything off in the docs: feedback is welcome!
