**kwargs question

[DPaul]

Here is an example to calculate circumference of a shape

def circumference(**kwargs):
        return 2 * math.pi * kwargs['radius'] 

Dear Buran,

This is exactly what i thought should be possible. Thanks.
I tried many variations, somehow i missed the simplest.
The question remains, why all other **kwarg examples show little "added value".
This one does. It is powerful.

Thanks
Paul
