A function with no explicit return statement returns the non value None.

Your shape.describe function sets an internal description, but has no 
return value.

Note that your author_name member function has the same issue as the 
describe function.

It might also be useful to distinguish between setter and getter 
functions:

    def set_describe(self,text):
        self.description = text
        
    def set_author_name(self,text):
        self.author = text

    def get_describe(self):
        return self.description
        
    def get_author_name(self):
        return self.author
