more questions...(strings)

[p.s]

Hi again,
I've gotten some practice reading strings from files, and using raw_input,
and now I'm looking into splitting strings.
I know how to get something like "hello at there", split by doing
str.split("@"), and I get a list of ["hello", "there"].
However, I'm trying to get two lists, the first with the string before the
"@", and the second list with the remainder of the string.

So if i read from a file with:
one at two
white at black
left at right
I'd end up with this:
list_one = ["one", "white", "left"]
list_two = ["two", "black", "right"]

thanks for reading.
