Put your top level code inside of a try/except block:

if __name__ == "__main__":
  try:
    main()
  except:
    # something unexpected happened so reinit the hardware
    reinitialize()
    raise

The call to reinitialize() will be done before Python does
its cleanup so there will be no problems because of that.
