An example of an AI chatbot conversation about type checking in Python.
How can I use type checking in Python?
You can use type hints in Python to indicate the expected data types of function arguments and return values.
Can you show me an example of type hints in a function?
Sure! Here's a simple example:
def add_numbers(a: int, b: int) -> int:
return a + b
What if I pass the wrong type of argument?
If you pass the wrong type, Python won't raise an error at runtime, but tools like mypy can help catch these issues during development.
Are there any built-in functions for type checking?
Yes, you can use the isinstance() function to check the type of an object at runtime.
