Actually I changed it even more since last.

for i in in_file:

This does what I need with the excpetion that it dosent do it for every
line.  It is currous because it will take off a <cr> from one line and not
the next 2 and then from another line...  currious...

What happens if you don't put the \n back on?
As it stands you are stipping off one character with the [:-1]
and putting another on with the +'\n'. Maybe just leaving
off the \n will do what you want?

BTW The Tkinter stuff is doing nothing useful so far, it's
just adding confusion to the code. You might be better
stripping it out until you are ready to use it.
