"""Python.Interpreter COM Server
|
||
|
|
|
||
|
|
This module implements a very very simple COM server which
|
||
|
|
exposes the Python interpreter.
|
||
|
|
|
||
|
|
This is designed more as a demonstration than a full blown COM server.
|
||
|
|
General functionality and Error handling are both limited.
|
||
|
|
|
||
|
|
To use this object, ensure it is registered by running this module
|
||
|
|
from Python.exe. Then, from Visual Basic, use "CreateObject('Python.Interpreter')",
|
||
|
|
and call its methods!
