Putting len(os.linesep)'s value into a local variable will make accessing
it quite a bit faster. But why would you want to do that?

You mentioned "\n" translating to two lines, but this won't happen. Windows
will not mess with what you write to your file. It's just that
traditionally windows and windows programs use \r\n instead of just \n. I
think it was for compatibility with os/2 or macintosh (I don't remember
which), which used \r for newlines.

You don't have to follow this convention. If you open a \n-separated file
with *any* text editor other than notepad, your newlines will be okay.
