What are decorators with parameters in Python?

Can you explain what decorators with parameters are in Python?

Sure! Decorators with parameters are a way to modify the behavior of a function or method by wrapping it with another function that takes arguments.

How do you create a decorator that takes parameters?

To create a decorator with parameters, you define a function that returns a decorator function. The outer function takes the parameters, and the inner function takes the original function.

Can you give me a simple example?

Absolutely! Here's a basic example:

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}!')

What happens if I don't pass parameters to the decorator?

If you don't pass parameters, the decorator will not function as intended, and you may encounter errors or unexpected behavior.
