In short: They have inherited "object" from somewhere. (This is probably technically inaccurate, but it's the only thing I have seen which defines a 'new-style class'). What it means *practically*, is that you can use properties. For a long while I didn't really understand the point or properties, until I needed them. I have written a flowcharting application in Python. All objects on the flowchat are derived from a base object which has the attribute "text" (all objects have some form of, sometimes internal only, title). Problem is that when some objects change text, I want to perform some recalculations. So I wrote a "text" property, which - in its settext-method - does all the calculations if required. That way, the application can till use: obj.text = 'Blah' ..and still have the chance to act on the text change. I could have simply written a setText() method, but imho properties are neater - but that's just a matter of opinion. -- Kind Regards, Jan Danielsson Te audire no possum.
