How do I create a parameterized decorator in Python?

To create a parameterized decorator, you need to define a function that returns a decorator function. Here's a simple example:

Can you show me a code example?

Sure! Here's a basic example:

def my_decorator(param):
    def decorator_function(func):
        def wrapper(*args, **kwargs):
            print(f'Parameter: {param}')
            return func(*args, **kwargs)
        return wrapper
    return decorator_function

@my_decorator('Hello')
def greet(name):
    print(f'Greetings, {name}!')

# Usage

# greet('Alice') will print:
# Parameter: Hello
# Greetings, Alice! 

What are some use cases for parameterized decorators?

Parameterized decorators can be used for logging, access control, caching, and modifying function behavior based on parameters.
