What are the differences between typing extensions and annotations in Python?
Typing extensions are additional features for type hints in Python, while annotations are the basic syntax for type hints.
Can you give me examples of both typing extensions and annotations?
Sure! An annotation example is def func(x: int) -> str:. A typing extension example is using from typing_extensions import Literal.
When should I use typing extensions instead of regular annotations?
Use typing extensions when you need features not available in the standard typing module, like TypedDict or Literal.
