How can I debug Python decorators effectively?

Debugging Python decorators can be tricky. You can use print statements or logging to trace the flow.

Can you show me an example of using print statements in a decorator?

Sure! Here's a simple decorator that prints the arguments and return value:

def debug_decorator(func):
    def wrapper(*args, **kwargs):
        print(f'Calling {func.__name__} with {args} and {kwargs}')
        result = func(*args, **kwargs)
        print(f'{func.__name__} returned {result}')
        return result
    return wrapper

What if my decorator is more complex? How can I debug that?

For complex decorators, consider using a debugger like pdb or adding more detailed logging to track the execution.

Are there any tools specifically for debugging decorators?

Yes, tools like PyCharm have built-in debugging features that can help you step through your decorators.
