[Python-Dev] Confusing listreverseiterator Behavior (original) (raw)

Unless I'm misconstruing something the problem is that reversed returns two different object types depending on if it's a list or a tuple

l = [1,2,3,4] i = iter(l) ri = reversed(l) l [1, 2, 3, 4] ri <listreverseiterator object at 0x00D5C8F0> i <listiterator object at 0x00D5C3F0> t = (1,2,3,4) it = iter(t) rit = reversed(t) it <tupleiterator object at 0x00D5C030> rit <reversed object at 0x00D5CC90>

reversing a tuple (or a string) returns a "reversed object" reversing a list returns a "listreverseiterator"
