How do decorators with parameters work in Python?

Can you explain how decorators with parameters work in Python?

Sure! A decorator with parameters is a function that takes another function as an argument and can also take additional arguments.

Can you give me an example of a decorator with parameters?

Absolutely! Here's a simple 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}!')

This will print the greeting three times.

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

If you don't pass parameters, the decorator will not function as intended. It will raise an error unless it's designed to handle that case.
