Noted. I am at the moment trying TextWrangler for editing Python. May be I will
revert to Idle.

It is a shame, though. Xcode is a great python environment, as far as my
experience goes. It would be far more useful if it were open source.

Yes. This is the example from the Apple web site
(http://developer.apple.com/cocoa/pyobjc.html).
I did find the error, though, and it is an xcode peculiarity/bug. Namely, when
you create a new Python class file in xcode it doesn't get added to "Classes"
in the xcode project. You have to drag it there manually.

I have installed the Python 2.5 for OS X from python.org. And I have this now

==================
muhammad-alkarouris-computer:~ malkarouri$ which python
/Library/Frameworks/Python.framework/Versions/Current/bin/python
muhammad-alkarouris-computer:~ malkarouri$ ls -l /usr/local/bin/python
lrwxr-xr-x   1 root  wheel  68 Oct 15 06:13 /usr/local/bin/python ->
../../../Library/Frameworks/Python.framework/Versions/2.5/bin/python
muhammad-alkarouris-computer:~ malkarouri$ echo $PATH
/Library/Frameworks/Python.framework/Versions/Current/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/teTeX/bin/i386-apple-darwin-current
muhammad-alkarouris-computer:~ malkarouri$ cat .bash_profile 

# Setting PATH for MacPython 2.5
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/Current/bin:${PATH}"
export PATH
muhammad-alkarouris-computer:~ malkarouri$ 
==================

So, the installer did install /usr/local/bin/python. Through .bash_profile,
python2.5 is the default for my shell, while python2.3 is the default for
everything else. This is fine by me. I assume that is the right approach. Or is
there another installer?

Keep up the good work. For now, PyObjC 1.4 source installation for both Python
2.5 and Python 2.3 are working fine.

Thanks again,
