Python Project Structure: Best Practices for 2026

The ideal Python project structure for 2026.

Recommended Layout

my_project/
  src/
    my_package/
      __init__.py
      core/
        engine.py
      api/
        routes.py
      utils/
        helpers.py
  tests/
    test_core.py
  pyproject.toml
  README.md
Enter fullscreen mode Exit fullscreen mode

Key Principles

  1. src layout - Avoids import issues
  2. Type hints - Always use type annotations
  3. Pydantic models - For data validation
  4. Async by default - Use async/await for I/O
  5. Testing - pytest with fixtures

Modern Dependencies (2026)

[project]
dependencies = [
    "pydantic>=2.0",
    "httpx>=0.25",
    "uvicorn>=0.20",
]
Enter fullscreen mode Exit fullscreen mode
