Summary: Characters property does not have __call__ method

Initial Comment:
The Characters property/method is supposed to allow an
application to modify the contents (in whole or in
partial) of a cell, text box, etc.  According to the
Microsoft Excel Object Model, Characters has two
optional arguments, one to specify the starting
position and a second to specify the number of
characters (default is for the whole set).  When I try
to call Characters of an object such as an AxisTitle or
Cell, python fails with an error like so:

<--
Traceback (most recent call last):
  File "__init__.py", line 546, in ?
    y2axis.AxisTitle.Characters(2,2).Font.Subscript = True
AttributeError: Characters instance has no __call__ method
-->

The way that a call like this should work can be easily
implemented within Excel's Visual Basic Editor with an
open sheet named "Sheet1":
<--
Function demonstration()
    Sheet1.Cells(1,1).Value = "test phrase"
    Sheet1.Cells(1,1).Characters(1,4).Font.Bold = True
End Function
-->
This script places the value "test phrase" into the
first cell on Sheet1, and then makes only the "test"
part bold.  I have made a python script which attempts
to do the same thing as an example but fails on the
call to Characters.

Software versions:
Python 2.3.2
win32com build 203
Microsoft Excel 2002 (10.4302.4219) SP-2

Thanks!  That's just what I was looking for.

Is there a better way to find information like this, like
documentation or source code or something?  I tried (among
other things) looking in the makepy wrapper .py file but it
was rather confusing and not very helpful.

The Characters property is a "parametrized" property. 
Such a concept is not natively supported by Python.
With a makepy wrapper you could call 

 y2axis.AxisTitle.GetCharacters(2,2).Font.Subscript = True

So just a little bit different interpretation of an
interface definition.
