Since nobody here seems to want to answer your question
(or seems even able to read it), I'll try.  Is something 
like this what you want?

import re

texts = [
    '(i)"In the ocean"',
    '(ii)"On the ocean"',
    '(iii) "By the ocean"',
    '(iv) "In this group"',
    '(v) "In this group"',
    '(vi) "By the new group"']

pattern = re.compile (r'^\((.*)\)\s*"\S+\s*(.*)\s\S+"$')
for txt in texts:
    matchobj = re.search (pattern, txt)
    number, midtext = matchobj.group (1, 2)
    print ("(%s) %s" % (number, midtext))
