But with vim once you close the file it deletes the temporary copy.
So unless you realize the problem before it gets deleted it won't help.
But since you are using IDLE I don;t think that's even an option.
So far as i know IDLE doesn't create a backup file.

It will keep all the versions that you check in. so if you create an
editor macro (assuming you have an editor that does macros
 - IDLE doesn't...) that checks in the file each time you save it
then you can roll back to any intermediate save.

That's not strictly true, it depends on the VCS (and even  server
based ones can be used locally if needed). I still use RCS for my
own projects and that's just a local file (or more usually a folder
called RCS...) CVS and SVN can both work with local files if you
want something beefier than RCS.
