As documented the 'sort_on_ parameter must be a *sequence* of sorting 
definitions and a *single* sorting
definition. This should work:

 sort_on =(('self', test, 'desc'),)

  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

David
