What are the differences between type hints and dynamic typing in Python 3.10?

In Python 3.10, type hints provide a way to indicate the expected data types of variables, while dynamic typing allows variables to change types at runtime. Type hints are optional and mainly serve for better code readability and static analysis.

Can you give me an example of type hints in Python?

Sure! Here's a simple example:

def greet(name: str) -> str:
    return f'Hello, {name}!'

In this function, name is expected to be a string, and the function returns a string.

What are the benefits of using type hints?

Type hints improve code clarity, help with static type checking, and can enhance IDE support, making it easier to catch errors before runtime.

Is dynamic typing still useful in Python?

Yes, dynamic typing allows for more flexibility in coding, enabling rapid development and easier prototyping, especially in smaller scripts.
