This is a perfectly OK way to write this, but personally I find my eyes 
start to glaze over whenever I see things like \(\(, so I would probably 
have written it as \({2}.  I find that a little easier to read.  So, for 
the whole thing up to this point:

     \({2}[^)]+\){2}

although, even better would be to use to utterly awesome re.VERBOSE 
flag, and write it as:

     \({2} [^)]+ \){2}
