Rename symbolic link in python

I would like to know is it possible to rename a symlink with python.

Already tried os.rename and shutil.move

Any ideas?

os.rename return me this error : OSError: [Errno 18] Cross-device link

>>> import sys, os
>>> 
>>> path = '/Library/Application Support/appsolute/MAMP PRO/db/'
>>> job = path + 'mysql-job/'
>>> perso = path + 'mysql-perso/'
>>> mysql = path + 'mysql/'
>>> 
>>> os.rename(mysql, job)

Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    OSError: [Errno 18] Cross-device link
>>> exit()

Danny-Dombrowski:script ddombrowski$ ls -al /Library/Application\ Support/appsolute/MAMP\ PRO/db/

os.rename will work fine:

$ ln -s target link
$ python -c "import os; os.rename('link', 'link.new')"
$ ls -l link.new
lrwxrwxrwx 1 phihag phihag 6 Feb  8 01:25 link.new -> target

Make sure you don't include a / after the symlink: link/ is the same as link/., and not the same as link.

os.rename should work.
