Er, yes, if you don't mind (a) mangling any string that *doesn't* have a
newline as the last character, and (b) messing up any subsequent part of
your program that tries to use the built-in str() function (because you just
reassigned that name to something else).

I'd suggest:

    foo = linestring.rstrip("\n")

You can also add to the quoted string any other characters you want to have
stripped; for example,

    foo = linestring.rstrip("\n\r\t")

Or if you want to strip off *all* whitespace characters, just leave it out:

    foo = linestring.rstrip()
