I have a multi-line string defined like this:

foo = """
this is 
a multi-line string.
"""

I need an iterator that iterates over the individual lines of that string. I could of course do it like this:

lineiterator = iter(foo.splitlines())

Is there a more direct way of doing this? In this scenario the string has to traversed once for the splitting, and then again by the parser. It doesn't matter in my test-case, since the string is very short there, I am just asking out of curiosity. Python has so many useful and efficient built-ins for such stuff, but I could find nothing that suits this need.
