+# Python Language Prompt Snippet
+
+## Key Concepts
+
+- **Decorators**: Functions that wrap other functions or classes using `@decorator` syntax
+- **List/Dict Comprehensions**: Concise syntax for creating collections from iterables
+- **Generators and Yield**: Lazy iterators using `yield` for memory-efficient data processing
+- **Context Managers**: `with` statement for resource management via `__enter__`/`__exit__`
+- **Type Hints and Typing Module**: Optional static type annotations for tooling and documentation
+- **Dunder Methods**: Special methods like `__init__`, `__repr__`, `__eq__` defining object behavior
+- **Metaclasses**: Classes that define how other classes are created (type as default metaclass)
+- **Dataclasses**: `@dataclass` decorator auto-generating boilerplate from field annotations
+- **Protocols**: Structural subtyping via `typing.Protocol` for duck-type-safe interfaces
+- **Descriptors**: Objects defining `__get__`, `__set__`, `__delete__` to customize attribute access
+- **Async/Await with Asyncio**: Cooperative concurrency using coroutines and an event loop
+
+## Import Patterns
+
+- `from module import name` — import specific name from module
+- `import module` — import entire module, access via `module.name`
+- `from package.module import name` — absolute import from nested package
+- `from . import relative` — relative import within a package
+
+## File Patterns
+
+- `__init__.py` — package initializer (barrel equivalent), can re-export public API
+- `__main__.py` — package entry point when run with `python -m package`
+- `conftest.py` — pytest shared fixtures and hooks (auto-discovered)
+- `setup.py` / `pyproject.toml` — project configuration and build metadata
+- `requirements.txt` — pinned dependency list
+
+## Common Frameworks
+
+- **Django** — Full-stack web framework with ORM, admin, and batteries included
+- **FastAPI** — Modern async API framework with automatic OpenAPI docs
+- **Flask** — Lightweight WSGI micro-framework for web applications
+- **SQLAlchemy** — SQL toolkit and ORM with unit-of-work pattern
+- **Celery** — Distributed task queue for background job processing
+- **Pydantic** — Data validation and settings management using type annotations
+
+## Example Language Notes
+
+> Uses `@dataclass` decorator to auto-generate `__init__`, `__repr__`, and `__eq__` from
+> field annotations. This eliminates boilerplate while keeping the class definition
+> readable and the generated methods consistent.
+>
+> When `__init__.py` re-exports symbols, it acts as the package's public API surface —
+> consumers import from the package rather than reaching into internal modules.
