 ... 
 import win32com.client 
 ... 
 class Python_skript(Object): 
  
    def __init__(self, fileName=None): 
       self.xlapp = win32com.client.dynamic.Dispatch("Excel.Application") 
       if fileName: 
          self.xlbook = self.xlapp.Workbooks.Open(fileName) 
       else: 
          self.xlbook = self.xlapp.Workbooks.Add() ... 
 **********************************************************
 
  
 I got the error message: "ImportError: No system modul 'pythoncom' (pythoncom24.dll)"
