What are some advanced features of typing in Python?
Python's typing module includes advanced features like TypeVar, Generic, and Protocol for more flexible type hints.
Can you explain how TypeVar works?
TypeVar allows you to create a generic type that can be used in functions or classes, enabling type flexibility.
What about Protocol? How is it different from an interface?
Protocol defines a set of methods and properties that a class must implement, similar to interfaces in other languages, but it's more flexible.
Are there any practical examples of using these features?
Yes, you can use TypeVar in a function that works with multiple types, and Protocol can help define expected behaviors in classes.
