    "1. You saw before that a Python list can contain practically anything; even other lists! To subset lists of lists, you can use the same technique as before: square brackets. Try out the commands in the following code sample in the IPython Shell: x = [[\"a\", \"b\", \"c\"], [\"d\", \"e\", \"f\"], [\"g\", \"h\", \"i\"]]. x[2][0], x[2][:2]. x[2] results in a list, that you can subset again by adding additional square brackets. What will house[-1][1] return? house, the list of lists that you created before, is already defined for you in the workspace. You can experiment with it in the IPython Shell.\n",
