Hello,
I'm french and I have a small sorting problem with python (and zope's
zcatalog):
In a python shell python, try :
'é' > 'z'
The answer is true. Then if you try
test=['a','b','f','é','z']
print test.sort()
You almost get :
['a','b','f','z','é']
That's not what we want :-)
Any help will be greatly appriciated.
PS : I got the same behaviour with zope's zcatalog during a sort_on request.
Even if I start zope with the correct linux locale (fr_FR).
THX

Thank you very much Peter, that's a really great tip. You should try to
publish this one on the Internet 'cause I didn't find any web site
explaining this.
Bye.

Peter what about using this kind of tip with cmp() built-in ??
def myCompare(self,a,b):
cmp(a,b)
with a and b being french accented chars ???
Any idea ??
Thanks again.

From the documentation of the locale module:
"""
strxfrm(string)
Transforms a string to one that can be used for the built-in function cmp(),
and still returns locale-aware results. This function can be used when the
same string is compared repeatedly, e.g. when collating a sequence of
strings.

Peter
Note however that you need to transform both strings being compared...
e.g., with a french locale: 'd' < '\xe9'
True 'f' < '\xe9'
True 'd' < locale.strxfrm('\xe9')
False 'f' < locale.strxfrm('\xe9')
False locale.strxfrm('f') < locale.strxfrm('\xe9')
False locale.strxfrm('d') < locale.strxfrm('\xe9')
True
