An example of an AI chatbot conversation about type safety in Python.
What is type safety in Python?
Type safety in Python refers to the enforcement of type constraints on variables and functions, ensuring that operations are performed on compatible data types.
How does Python achieve type safety?
Python uses dynamic typing, but with type hints introduced in PEP 484, you can specify expected types, which helps with type safety during development.
Can you give me an example of type hints in Python?
Sure! Here's a simple example:
def add_numbers(a: int, b: int) -> int:
return a + b
This function specifies that both parameters should be integers and the return type is also an integer.
What are the benefits of using type hints?
Type hints improve code readability, help catch errors early with static type checkers, and enhance IDE support for better autocompletion.
