What are some examples of metaprogramming in Python?

Metaprogramming in Python allows you to write code that manipulates code. Examples include decorators, metaclasses, and the use of the type() function.

Can you explain how decorators work in Python?

Sure! Decorators are functions that modify the behavior of another function. They are often used for logging, access control, or modifying input/output.

What about metaclasses? How do they differ from regular classes?

Metaclasses are classes of classes. They define how a class behaves, allowing you to customize class creation and modify class attributes.

Can you give me a simple example of a decorator?

Absolutely! Here's a simple example:

def my_decorator(func):
    def wrapper():
        print('Something is happening before the function is called.')
        func()
        print('Something is happening after the function is called.')
    return wrapper

@my_decorator
def say_hello():
    print('Hello!')

say_hello()
