What are advanced type hints in Python?
Advanced type hints in Python include features like TypeVar, Union, Optional, and Callable, which enhance type safety.
Can you explain how to use TypeVar?
Sure! TypeVar allows you to create generic types. For example, you can define a function that works with any type.
What about using Union and Optional?
Union lets you specify multiple types for a variable, while Optional is a shorthand for Union with None, indicating a value may be absent.
How do I use Callable in type hints?
Callable is used to specify the type of a function. You can define the argument types and return type for better clarity.
