Use \1 to refer to the group in the substitution expression.
You also need to change the regex to non-greedy match (the trailing ?).
Otherwise you only get one big match from .taken ... not.
s = ("been .taken. it may be .left. there, "
"even if the .live coals were not. cleared")
r = re.compile(r"\.(.*?)\.")
print r.sub(r".start \1 end.", s)
