10# Python Project Conventions
11
12## Environment & Tooling
13- Python 3.11+ required
14- `uv` for dependency management and virtual environments
15- `ruff` for linting and formatting (replaces black, isort, flake8)
16- `mypy --strict` for type checking
17- `pytest` for testing
18
19## Code Style
20- Type hints required on all function signatures — parameters and return types
21- Line length: 88 characters (ruff default)
22- Imports: stdlib → third-party → local, sorted automatically by ruff
23- Google-style docstrings for public API only — not private methods
24
25## Naming
26- `snake_case` for functions, variables, modules
27- `PascalCase` for classes
28- `UPPER_SNAKE_CASE` for module-level constants
29- No abbreviations in names (`user_id` not `uid`, `connection` not `conn`)
30
31## Patterns to Follow
32```python
33# ✅ pathlib over os.path
34config_path = Path(__file__).parent / "config.yaml"
35
36# ✅ dataclass for structured data
37@dataclass
38class OrderItem:
39 product_id: str
40 quantity: int
41 price: Decimal
42
43# ✅ specific exceptions with context
44try:
45 result = process(data)
46except ValueError as e:
47 raise ProcessingError("Invalid input format") from e
48```
49
50## Project Structure
51```
52src/
53 mypackage/
54 __init__.py # Explicit __all__ defining public API
55 core.py
56 models.py
57tests/
58 conftest.py
59 test_core.py
60pyproject.toml # All tool config lives here
61```
62
63## What to Avoid
64- Never use `except:` or `except Exception:` without re-raising or logging
65- No mutable default arguments: `def f(items=None)` not `def f(items=[])`
66- No `import *`
67- No `print()` for logging — use the `logging` module or `structlog`
