This sounds like you are getting into the fun depths of unix signal handling, http://docs.python.org/library/signal.html
One point of relevance on that page: "When a signal arrives during an I/O operation, it is possible that the I/O operation raises an exception after the signal handler returns. This is dependent on the underlying Unix system's semantics regarding interrupted system calls." You could install your own signal handler, but you'd still get this problem. Have you considered simply using "python -m pdb myscript"? Ctrl+c will drop into the debugger which allows you to quit or resume. I think it essentially uses sys.excepthoook to call settrace, so you could use your own there. mick On Mon, Jan 5, 2009 at 15:38, Daniel Kersten <[email protected]> wrote: > > Hi & happy new year, > > I'm wondering if theres anyway of resuming after a KeyboardInterrupt > exception, if I catch it.
