Python Software Patterns

A growing collection of design patterns and examples for Agentic coding instructions. These patterns help structure prompts and build robust, reusable solutions when working with coding agents. Each pattern demonstrates a specific technique for solving common software design problems.

Decorators

Function wrappers for extensibility and composability

Context Managers

Resource management with `with` statement

Descriptors

Reusable property-like behavior for attributes

Refactoring

Improving code structure without changing behavior

Magic Methods

Dunder methods for custom behavior

Protocols

Structural subtyping with duck typing and type safety

Generators

Lazy evaluation with yield and itertools

Metaclasses

Class creation hooks and runtime class generation

Functools

Caching, partial functions, and function utilities

Async/Await

Asyncio patterns, coroutines, and concurrent I/O

Slots

Memory optimization with __slots__

Concurrency

Threading, multiprocessing, and concurrent.futures
