What are the benefits of type annotations in Python?
Type annotations in Python improve code readability, help with debugging, and enable better tooling support.
Can you give me an example of how to use type annotations?
Sure! For instance, you can define a function like this: def add(a: int, b: int) -> int:
which specifies that both parameters and the return value are integers.
Do type annotations affect performance?
No, type annotations are not enforced at runtime, so they don't impact performance. They're mainly for static analysis.
Are there any downsides to using type annotations?
One downside is that it can add extra verbosity to your code, and it may require additional learning for new developers.
