Uncommon Uses of Python in Commonly Used Libraries (2022)

10 months ago

Python's `super()` function is essential for cooperative multiple inheritance, especially in base classes.
Mixin classes provide reusable functionality without state, ideal for optional features across multiple classes.
Relative imports (using `.`) ensure Python searches the current package first, preventing module conflicts.
Non-empty `__init__.py` files can simplify APIs, refactor code without breaking changes, and initialize package-wide resources.
Class methods are used when needing class-level operations, while static methods serve as utility functions within a class's namespace.
`conftest.py` in pytest not only provides fixtures but also helps in modifying `sys.path` for module recognition.
Design principles in libraries like scikit-learn emphasize consistency and composition, while PyTorch focuses on pragmatic performance and simplicity.
