You could reverse the string via slicing and (for Python 3) use str.translate with the appropriate str.maketrans mapping:
str.translate
str.maketrans
>>> s = "test (with (w)ords) swap"
>>> s[::-1].translate(str.maketrans('()', ')('))
'paws (sdro(w) htiw) tset'
This work for python2:
from string import maketrans
reversed = myString[::-1].translate(maketrans(")(", "()"))
Output:
paws (sdro(w) htiw) tset
