What are some advanced topics I can explore in Python?

You can explore topics like decorators, generators, context managers, and metaclasses. Which one interests you?

Tell me more about decorators.

Decorators are a way to modify or enhance functions or methods without changing their code. They are often used for logging, access control, and caching.

Can you give me an example of a simple decorator?

Sure! Here's a simple decorator that prints the function name before executing it:

def my_decorator(func):
    def wrapper():
        print(f'Calling {func.__name__}')
        return func()
    return wrapper

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

say_hello()  # This will print 'Calling say_hello' followed by 'Hello!'

What about generators? How do they differ from regular functions?

Generators allow you to iterate over a sequence of values without storing them all in memory at once. They use the yield statement to produce a value and pause the function's state.
