No.
 >>> ''.join(list(reversed('abc')))
'cba'
 >>> 'abc'[2::-1]
'cba'
 >>> 'abc'[1000000000::-1]
'cba'

Any int >= len(string)-1 will do, so the call to len will usually not be 
necessary.

Needing strings reversed is not common.  More common might be

for char in reversed(somestring): process(char)
