[Tutor] Sort a Set

[Jonas Melian]

I get a list of repeated numbers  [24, 24, 24, 16, 16, 15, 15 ]
Is possible get it without repeated numbers, without using set()?

If I use set, then the list is unsorted and i cann't sorting it.

For get the values i use:

[x[0] for x in cardTmp]

or:

from itertools import imap
for i in imap(lambda x: x[0], cardTmp): print i

A idea it would be create a generator that will return elements one by 
one, and then it would be possible know if that element is in the new 
list. But generators are in 2.4
