What are decorators in Python and how do they work with function parameters?

Can you explain what decorators are in Python?

Sure! Decorators in Python are a way to modify or enhance functions or methods without changing their actual code.

How do decorators work with function parameters?

Decorators can accept parameters themselves, allowing you to customize their behavior based on the arguments passed to the decorated function.

Can you give me an example of a decorator that takes parameters?

Absolutely! Here's a simple example: a decorator that repeats a function's output a specified number of times.

That sounds interesting! Can you show me the code for that?

Sure! Here's the code:

def repeat(num_times):
    def decorator_repeat(func):
        def wrapper(*args, **kwargs):
            for _ in range(num_times):
                func(*args, **kwargs)
        return wrapper
    return decorator_repeat

@repeat(3)
def greet(name):
    print(f'Hello, {name}!')

# Calling greet('Alice') will print 'Hello, Alice!' three times.
