Can decorators return values in Python?

Can decorators return values in Python?

Yes, decorators can return values. They can modify the behavior of a function and return a new value.

Can you give me an example of a decorator that returns a value?

Sure! Here's a simple example:

def my_decorator(func):
    def wrapper():
        return func() + 1
    return wrapper

@my_decorator
def my_function():
    return 5

result = my_function()  # This will return 6

What happens if the decorator doesn't return a value?

If a decorator doesn't return a value, the original function will return None by default, unless specified otherwise.

Are there any built-in decorators in Python that return values?

Yes, built-in decorators like @staticmethod and @classmethod can modify methods and return values based on their context.
