What is type guarding in Python 3.10?
Type guarding in Python 3.10 allows you to enforce type checks at runtime, improving code safety.
Can you give me an example of how to use type guards?
Sure! You can define a type guard function that checks the type of a variable and narrows its type accordingly.
How does it differ from regular type hints?
Type hints are static and only provide information to the type checker, while type guards enforce checks at runtime.
Are there any performance implications of using type guards?
Yes, using type guards can introduce some overhead due to runtime checks, but they enhance type safety.
