only if you type it into the interactive prompt. see: http://www.python.org/doc/2.4/tut/node5.html#SECTION005110000000000000000 "In interactive mode, the last printed expression is assigned to the variable _. This means that when you are using Python as a desk calculator, it is some- what easier to continue calculations /.../" the "_" symbol has no special meaning when you run a Python program, so the "if re.search" construct won't work. </F> -- http://mail.python.org/mailman/listinfo/python-list
