Why does this set comprehension...
>>> {2**x for x in {0,1,2,3,4,5}}
Produce this answer?
{32, 1, 2, 4, 8, 16}
BUT!
This loop...
>>> for x in {0,1,2,3,4,5}:
... print 2**x

`{0,1,2,3,4,5}` happens to be iterated over in ascending order. However, the resulting `set` isn't ordered any more. If you did a list comprehension instead of a set comprehension, you'd see the difference. – Tim Pietzcker Jul 01 '13 at 06:51

1Try `for x in {5,4,3,2,1,0}` too. It's not safe to rely on the order or sets. If you loop over the same set twice without adding/removing elements, you will get the same order, but that's about it. – John La Rooy Jul 01 '13 at 06:59
