problem with pydoc under python 2.6.1

[steve.ferg.bitbucket]

Has anybody encountered problems running pydoc with version 2.6.1?
I'm getting an error message that pydoc cannot import namedtuple
(details below).
(I'm running under 64-bit Windows Vista, although that probably is not
important.)

Here's my batch file, pydoc_test.bat:
=========================================================
@echo on
set pyver=python25
python c:\%pyver%\Lib\pydoc.py -w easygui

set pyver=python26
python c:\%pyver%\Lib\pydoc.py -w easygui
=========================================================

Here's what I get:
=========================================================
c:\pydev\easygui\v086>pydoc_test.bat

c:\pydev\easygui\v086>set pyver=python25

c:\pydev\easygui\v086>python c:\python25\Lib\pydoc.py -w easygui
wrote easygui.html

c:\pydev\easygui\v086>set pyver=python26

c:\pydev\easygui\v086>python c:\python26\Lib\pydoc.py -w easygui
Traceback (most recent call last):

sorry, it's OK.
My fault was using installed python to run development version's
library.
not sure about python26 for Windows...

Problem solved

Yinon's messages prompted me to take another look at my own code
(below). I realized that in the batch file I am looking for pydoc.py
in different locations for Python25 and Python26, but I am executing
python.exe without changing the path. Which means that I am executing
the same version of Python in both cases.

=========================================================
@echo on
set pyver=python25
python c:\%pyver%\Lib\pydoc.py -w easygui

set pyver=python26
python c:\%pyver%\Lib\pydoc.py -w easygui
=========================================================

The path was pointing to Python25, so when I ran against the 2.5
version of Pydoc it worked fine; when I ran against the 2.6 version of
Pydoc, I got an error.

I modified my batch file to also reset the PATH after pyver was set,
and then Pydoc worked fine in both cases.

Maybe somebody out there will find this an instructive mistake. My
thanks to Yinon; certainly for me his mistake was an instructive one.
