[Python] Report Lab Changing Paragraph Style

I have been struggling in an attempt to change the paragraph style in report lab. I think the issue is probably a lack of understanding what classes are. If anyone could give me some pointers that would be awesome. Bellow is my code. When I run it I get the error 'Error when calling the metaclass bases init() takes at most 3 arguments (4 given)'.

Cheers,

Robin
