python win32com and dispatchbaseclass

[vml]

I am a newbie in python and com. I am trying to use python and com to
access to a software.

I had a look in the file .py describing the interface (generated by
makepy) and I found some dispatch base class...

My fisrt question is : is it possible to invoke a com object dispatch
base class?


other question in vb 6 I do something like that :


Public Function GetMyXAxis(idata As foo.idata) As Double()
    Dim Block As foo.IBlock

    Set Block = idata

    GetMyXAxis = Block.XValues
    Set Block = Nothing

End Function


is it possible to do the set Block = idata  in python ?


foo.Iblock is a dispatchbaseclass
foo.idata is a dispatchbaseclass
