question involving installation of python applications

[Giancarlo Bassi]

Why python interpreter has two copies ?:

so that:

ls -l python*
-rwxr-xr-x 1 root root 2288515 Nov 10 13:41 python
lrwxrwxrwx 1 root root 16 Jul 3 02:06 python-config ->
python2.5-config
-rwxr-xr-x 1 root root 2288515 Nov 22 00:25 python2.3
-rwxr-xr-x 1 root root 1424 Jul 3 02:06 python2.5-config

---------------------------------------------------------------

If someone wants to keep more python interpreters how
can avoid to superpose them.

Only by renaming ?
Is there reference into documentation ?

I want to keep python 2.3.5 and Zope-2.8-final for FLE3 (future learning
environment) and install also pychess, requiring pygtk 2.x , (possibly for
python 2.5.1)

While I managed to install FLE3 , after installing python2.5.1
I didn't success to run again the daemon for running Zope-2.8.

I got somewhat like that:

aka-ankku@aka-ankku:/home/aka-ankku/Zope-2.8.0-final$ bin/zopectl
Traceback (most recent call last):

class BaseParser(xml.sax.ContentHandler):
AttributeError: 'module' object has no attribute 'ContentHandler'

Why 'module' object has no attribute 'ContentHandler' ?
