What are decorators with arguments in Python?

Can you explain what decorators with arguments are in Python?

Sure! Decorators with arguments 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 arguments?

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

def my_decorator(arg):
    def decorator(func):
        def wrapper(*args, **kwargs):
            print(f'Argument passed: {arg}')
            return func(*args, **kwargs)
        return wrapper
    return decorator

Can you show me how to use this decorator?

Absolutely! You can use the decorator like this:

@my_decorator('Hello')
def my_function():
    print('Function is called!')

my_function()  # This will print 'Argument passed: Hello' and 'Function is called!'

What are some common use cases for decorators with arguments?

Common use cases include logging, access control, and modifying input or output of functions.
