The help text is of little help if you don't know what is it talking about... The Python signal handler has additional information: you know *what* was being executed when the signal was caught (or nearly). A little example: import signal def babies(n): if n<=1: return 1 return adults(n-1) def adults(n): if n<=1: return 0 return adults(n-1)+babies(n-1) def fibom(n): return adults(n)+babies(n) def handler(signum, frame): print "At",frame.f_code.co_name, "in", frame.f_code.co_filename, "line", frame.f_lineno # Press CTRL-C to see what's being executed signal.signal(signal.SIGINT, handler) for n in range(50): print n, fibom(n) -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
