 .rsplit takes an optional "how many splits do you want?" parameter
 that defaults to giving you all of them.  Just ask for one
 right-most split:

  TESTS = [
     ("HELLO_xxxxxxx.lst", "HELLO"),
     ("HELLO_GOODBYE_xxxxx.ls", "HELLO_GOODBYE"),
     ]

  for input, expected in TESTS:
    result = input.rsplit('_', 1)[0]
    if result == expected:
      verdict = "passed"
    else:
      verdict = "failed"
    print "%r -> %r == %r  (%s)" % (
      input,
      result,
      expected,
      verdict,
      )
