Replace 2 characters within a reversed string at once

myString = "test (with (w)ords) swap"


reverse the string and swap ( with ) and ) with (

output: "paws (sdro(w) htiw) tset"

"paws (sdro(w) htiw) tset"

Is there a simple way to do this?

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
