As the others already mentioned list.reverse() is in-place, just as
for
example list.sort(). Alternatively, use the builtin reversed() or
sorted()
functions to get a return value (they will leave the original list
unmodified.

Example:
>>> a = range(3)
>>> b = reversed(a)
>>> for item in b:
      ...print item
This will produce:
  2
  1
  0

Note that reversed returns an iterator.
