Actually 'Script (Python)' Objects are methods of the container
just like a DTML method is. Its only a name. You can define
simple functions in them, its just like in python if you define
inner functions in a method (for example you cannot reference such
functions from outside of the 'Script (Python)' object.

Image this object like this: (only oversimplified example to show the idea!)

class Folder():
    def __init__(self,...):
        ...

    def yourPythonScript(self,args...):
        context=self
        container=context.aq_parent # out of my head. May be wrong but
                                    # for the sake of example
        here starts your Python Code in your Python Script.
