   You can use the array module to create character array objects and
retrive their addresses to use in Win32 API calls. There are examples of
this in python\pythonwin\pywin\scintilla\control.py such as:

def SCIInsertText(self, text, pos=-1):
    sma = array.array('c', text+"\0")
    (a,l) = sma.buffer_info()
    self.SendScintilla(SCI_INSERTTEXT, pos, a)

   Where 'a' is the address of the constructed array buffer object.
