How can I debug decorators in Python?

Debugging decorators can be tricky. You can start by adding print statements inside the decorator to trace execution.

What if I want to see the arguments passed to the decorated function?

You can modify the decorator to print the arguments before calling the function. Use *args and **kwargs to capture them.

Can you show me an example of a decorator that logs arguments?

Sure! Here's a simple example:

def log_args(func):
    def wrapper(*args, **kwargs):
        print(f'Arguments: {args}, {kwargs}')
        return func(*args, **kwargs)
    return wrapper

How do I apply this decorator to a function?

You can apply it using the @ symbol above your function definition like this:

@log_args
def my_function(x, y):
    return x + y
