re sub help

thanks for the reply.

i am still interested about using re, i find it useful. am still
learning it's uses.
so i did something like this for a start, trying to get everything in
between [startdelim] and [enddelim]

a =
"this\nis\na\nsentence[startdelim]this\nis\nanother[enddelim]this\nis\n"

t = re.compile(r"\[startdelim\](.*)\[enddelim\]")

t.findall(a)
but it gives me []. it's the "\n" that prevents the results.
why can't (.*) work in this case? Or am i missing some steps to "read"
in the "\n"..?
thanks.
