Do splitting and then reversing and then joining.

' '.join(string.split()[::-1])

Using split and reversed (a bit slower though):

>>> a
'Hey Gun'
>>> ' '.join(reversed(a.split()))
'Gun Hey'

This example has an intention that is more clear then the splicing example, i feel that in almost all cases that this example would be more maintainable and so gets a vote also. Maintainability is king, optimization overrated.
