how can i change the default python?

[=?ISO-8859-9?Q?Koray_Bostanc=FD?=]

Hi all,

When i type python in terminal it runs the python2.3 interpreter, but i
want to use 2.4 and Python2.4 package is already installed.

How can i change the default python in my system? I searched google for
a little but couldn't find.

Using Debian GNU/Linux.

"python" is usually merely a link on your "main" python distribution
(it's the same for many other things, gcc for example).

python (and all the python versions) are in /usr/bin for the deb'.

To rebind it, just remove the current link

$ rm /usr/bin/python

then create a new symbolic link to /usr/bin/python2.4

$ ln -s /usr/bin/python2.4 /usr/bin/python

(you may have to use *sudo* to perform these operations BTW)

Voila, you're done, calling python now starts the python2.4 interpreter.

Another thread touched on the dangers of doing this, if other
applications depend on the older version of Python.

Thanks for the hint Xavier.
I made the default interpreter ipython.

# rm /usr/bin/python
# ln -s /usr/bin/python2.4-ipython /usr/bin/python

ipython is better i think ..

and another question;
When i type "sudo aptitude install python-jabber" for example, it
brings the python2.3-jabber package. But i want it to bring me the 2.4
package. Of course i am able to use "sudo aptitude install
python2.4-jabber" but i want to know if this situation is normal? Can i
tell aptitude, bring me python2.4-xx when i type python-xx?

And running two version of python should be a problem?
