How does type checking work in Python?

Can you explain how type checking works in Python?

Sure! In Python, type checking is done at runtime, meaning that types are checked when the code is executed.

What are the different types of type checking in Python?

There are two main types: dynamic type checking, which occurs at runtime, and static type checking, which can be done using type hints and tools like mypy.

How do type hints improve type checking?

Type hints allow you to specify expected data types for function arguments and return values, making your code more readable and easier to debug.

Can you give me an example of using type hints?

Certainly! For example, you can define a function like this: def add(a: int, b: int) -> int: which indicates that both parameters and the return type are integers.
