How to retrieve the list of all characters defined as alphabetic for the
current locale ?

I think this is supposed to work, but not for whatever reason for me when I try to test after changing my locale (but I think that's a centos thing)...

import locale
locale.setlocale(locale.LC_ALL,'')
import string
print string.lowercase

I don't see where else this might be for python.

However, you can test if something is alpha:

>>> val = u'caf' u'\xE9'
>>> val.isalpha()
True
>>>

... and check its unicode category

>>> import unicodedata
>>> unicodedata.category(u'a')
'Ll' # Letter - lower case
>>> unicodedata.category(u'A')
'Lu' # Letter - upper case
>>> unicodedata.category(u'1')
'Nd' # Number - decimal?
>>> unicodedata.category(u'\x01')
'Cc' #


HTH,
