How can I debug decorators in Python?

You can debug decorators in Python by using print statements, logging, or a debugger like pdb to step through the code.

Can you show me an example of a decorator and how to debug it?

Sure! Here's a simple decorator that logs function calls:

def logger(func):
    def wrapper(*args, **kwargs):
        print(f'Calling {func.__name__}')
        return func(*args, **kwargs)
    return wrapper

To debug it, you can add print statements inside the wrapper function.

What if the decorator is more complex?

For complex decorators, consider using a debugger like pdb. You can set breakpoints inside the decorator to inspect variables and flow.

Are there any tools specifically for debugging decorators?

Yes, tools like PyCharm have built-in debugging features that allow you to step through decorators easily.
