What are some advanced techniques in Python programming?

Some advanced techniques include decorators, context managers, generators, and metaclasses. Would you like to explore one in detail?

Can you explain decorators?

Sure! Decorators are functions that modify the behavior of another function. They are often used for logging, access control, and caching.

How do I create a simple decorator?

To create a simple decorator, define a function that takes another function as an argument, and then define an inner function that adds functionality before or after calling the original function.

Can you show me an example?

Absolutely! Here's a basic 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()
