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.
