What are advanced usage scenarios for type hints in Python?
Advanced usage of type hints includes using generics, type variables, and custom types to enhance code clarity.
Can you explain how to use generics with type hints?
Sure! Generics allow you to define functions or classes that can operate on different types while maintaining type safety.
What are type variables and how do they work?
Type variables are placeholders for types that can be specified later, allowing for more flexible and reusable code.
Can you give an example of a custom type with type hints?
Absolutely! You can create a custom type using TypedDict
to define a dictionary with specific key-value types.
How do type hints improve code readability?
Type hints provide clear expectations for function inputs and outputs, making the code easier to understand and maintain.
