# Python Coding Style
> This file extends the common coding style rule with Python specific content.
## Standards
- Follow **PEP 8** conventions
- Use **type annotations** on all function signatures
## Immutability
Prefer immutable data structures:
```python
from dataclasses import dataclass
@dataclass(frozen=True)
class User:
name: str
email: str
from typing import NamedTuple
class Point(NamedTuple):
x: float
y: float
```
## Formatting
- **black** for code formatting
- **isort** for import sorting
- **ruff** for linting
## Reference
See skill: `python-patterns` for comprehensive Python idioms and patterns.
