Need a help on list....

[neeru29]

Let us assume that we have 4 different list which are independent of each other, But value in it are dependent of each other.


Say:-

List1 = [ ]
List2 = [ ]
List3 = [ ]
List4 = [ ]

i.e
value at List4[5] dependent with List1[5], List2[5], List3[5]

If i'm sorting List4 i don't want to loose the dependency of the values which are interconnected.

How can i do that..

Thanks in advance...

Create a copy of list4 for sorting.

def sorted(s, d=1):
    ''' Return a sorted copy of a list. If 'd' == -1,
    reverse the sort.'''
    def cmpitems(a, b):
        if d == 1:
            return cmp(a, b)
        return -cmp(a, b)
    s = s[:]
    s.sort(cmpitems)
    return s

list1 = ['d', 'a', 'c', 'x', 'y']
list2 = list1
list3 = list1
list4 =[list1[0], list1

list4_sorted = sorted(list4)

The sorted list will no longer be dependent on the other lists. You may be able to design a class object to maintain the dependency of several lists.
