Hi all:
I want to order a sequence using the Sequence sorting module from a 
Python script.
I have the following code:
"
seq = [['Bruzon', 'CUB'], ['Anand', 'IND'], ['Kasparov', 'RUS']]
def test(oneElem, twoElem):
    if oneElem[0] == twoElem[0]:
        return 0
    elif oneElem[0] > twoElem[0]:
        return 1
    else:
        return -1
sort_on =(('self', test, 'desc'))
return sequence.sort(seq, sort_on)
"
and i get the error:
"
Error Type: SyntaxError
Error
Value: sort option must contains no more than 2 fields

Leticia,
I tested this using a python script in Zope - and it seems to work.  
Nice to see someone doing something with Chess and Zope!

def test(x,y):
    if x[0] == y[0]:
        return 0
    elif x[0] > y[0]:
        return 1
    else:
        return -1

request = container.REQUEST

seq = [['Bruzon', 'CUB'], ['Anand', 'IND'], ['Kasparov', 'RUS']]

seq.sort(test)
print seq
