You could use a combination of split and join in this case.

#use a single quote as a seperator to split the string is a list of substrings
ls = s.split("'")

#remove what comes before the first and after the last single quote
ls = ls[1:-1]

#reassemble the string between the outermost single quotes.
s = "'".join(ls)

#strip spaces in front and after if you wish
s = s.strip()
