Hmmm, doesn't look to me as if it's worth much...:

s.join(s[::-1])'

since what you're doing is...:

>>> s = "onomatopoeia"
>>> s = s.join(s[::-1])
>>> s
'aonomatopoeiaionomatopoeiaeonomatopoeiaoonomatopoeiaponomatopoeiaoonoma
topoeiatonomatopoeiaaonomatopoeiamonomatopoeiaoonomatopoeianonomatopoeia
o'
>>>

...which isn't really just reversing the string, but quite a bit more
work!-)
