What are the differences between type annotations and docstrings in Python?
Type annotations specify the expected data types of function arguments and return values, while docstrings provide documentation about the function's purpose and usage.
Can you give me an example of each?
Sure! A type annotation example: def add(a: int, b: int) -> int:
. A docstring example: """Adds two numbers and returns the result."""
.
Why are both important in Python?
Type annotations help with type checking and improve code readability, while docstrings enhance documentation and usability for other developers.
Can type annotations replace docstrings?
No, they serve different purposes. Type annotations clarify data types, while docstrings explain the function's behavior and usage.
