What are advanced typing techniques in Python?
Advanced typing in Python includes features like TypeVar, Generic, and Protocol for more flexible type hints.
Can you explain how to use TypeVar?
TypeVar allows you to create a generic type that can be used in functions or classes. For example, T = TypeVar('T')
lets you define a function that can accept any type.
What about using Protocol for structural subtyping?
Protocol allows you to define a set of methods that a class must implement, enabling structural subtyping. This is useful for duck typing.
Are there any best practices for using these advanced typing features?
Yes, it's best to use typing to enhance code readability and maintainability, but avoid overcomplicating simple functions.
