Embedding Python: Creating Python Class from Application

[Kakacek]

Hello All,

Let's say I have a following python code:

class hw_class:
   def __init__(self):
       pass
   def hello_world(self):
       print 'Hello World!'
create_instance('hw_class', 'hw')
hw.hello_world()
hw = None

The 'create_instance' function should be implemented in the application
(powered by Delphi - P4D) which is embedding the Python.dll.

I am trying to do this for some time having no success. I am missing
these informations:
1. How to register global python variable from application which is
embedding python?
2. How to assign this variable with the class instance.
3. How to create the instance of class which is unknown at the compile
time.

Could someone supply the (C/Pascal) code fragment for this?

Thanx,

Jiri.
