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
