All right very quickly now let's go ahead and add some lines in this example dot txt
file and that process is called appending. Again you want to use open
method, and again you may point to an existing file or if the file doesn't
exist it will be created and the argument you want to pass now is a.
So that's stands for appending. As you can observe now in contrast to the previous
lecture our text file was emptied but in this case we still have these three
existing lines there. Again you use the write method to add anything in there.
Line 4 or whatever, and normally the changes haven't yet been reflected
in the atom editor, so you want to close that. And now you see Line 4 added in there.
Yeah, that was what I want to show you in this lecture and I'll see you later.
