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,

Emile

Thanks for the responses. Alas, neither solution works.

Under Ubuntu :

# ----------------------
import string
import locale

print locale.getdefaultlocale()
print locale.getpreferredencoding()

locale.setlocale(locale.LC_ALL, "")

print string.letters

letter_class = u"[" + u"".join(unichr(c) for c in range(0x10000) if
unichr(c).isalpha()) + u"]"

#print letter_class
# ----------------------

prints the following :


('fr_FR', 'UTF8')
UTF-8
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz


I commented out the letter_class printing for outputing a flood of 
characters not belonging to the usual french character set.


More or less the same problem under Windows, for instance, 
string.letters gives the "latin capital letter eth" as an analphabetic 
character (this is not the case, we never use this letter in true french 
words).
