[Tutor] deleting CR within files

[David Talaga]

Closer Roger,
But I noticed that it is taking off 2 character (obviously -2) from the last
and not touching the <cr>'s.  hrmmm. How would I get rid of those pesky
<cr>'s????

Rumor has it that David Talaga may have mentioned these words:

[snip]
>       out_file.write(i[:-1] + '\n') #maybe the problem is here?

If this is on a windows platform, you'll want this:

out_file.write(i[:-2] + '\n')
                  ^^^

For the more popular computers/OSs, this is what the line endings are:

Linux: \n only
MS-DOS / Winders: \r\n
MacOS (at least thru ver.9): \r only

So you need to lop off the last 2 characters of the string on Winders and
replace with a single \n for *nix machines; Your current code on Winders is
only replacing the last \n with a \n, which isn't quite what you want. ;-)

HTH,
