getenv/putenv

Bonjour,

Il y a un truc qui m'échappe, là :

marsu[pts/4]:~/{25}/> ipython 
Python 2.5.2 (r252:60911, Apr  7 2008, 01:11:55) 
Type "copyright", "credits" or "license" for more information.

IPython 0.8.3.svn.r3001 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object'. ?object also works, ?? prints more.

marsu[11:48:54]:~/{1}/> import os

marsu[11:48:57]:~/{2}/> os.getenv('LANG')
                Out[2]: 'fr_FR@euro'

marsu[11:49:05]:~/{3}/> os.unsetenv('LANG')

marsu[11:49:13]:~/{4}/> os.getenv('LANG')
                Out[4]: 'fr_FR@euro'

marsu[11:49:20]:~/{5}/> 

Une idée ?

Merci d'avance.
