> In python (and many other languages) some special characters that are not easy to represent have a code:
> LF : \n
> CR : \r
> TAB : \t
> So just add \n to to first line to add an eol: Text = "Hello World.\n" [Beware that inside python \n actually both means char #10 and 'newline', transparently, whatever the os uses as 'newline' code for text files. Very handy.]
