Debugging a script

[Graham Nicholls]

I've got a (python) program which crashes.  WHat I'd like to do is something
loke this:

        try:
                lots of stuff, or 
                more pertinintly, the code which is failing
        except:
                drop in to the debugger

So that I can print various things.

Also, is there a way to display the line number  - eg:
        except something:
                print ("DEBUG: exception %s at line number %s" % (sys.exc_type,
sys.linenumber))

Thanks
