Use the in operator to provide some flexibility to the castle game. Allow the player in the Courtyard to go "north" or "up" to the upper Hallway, or "down" or "south" to return to the Courtyard from the Hallway.

Note: Since this method requires the use of the in keyword, it’s asking that the answer make use of strings or collections that combine both direction possibilities. So in the Hallway example, to go north or up would be represented with the string “north up”, as seen below. Alternatively one could make use of a list of both words.

```

def pickRoom(direction , room):

#Set the direction to the "lower" of the direction
direction = direction.lower()

#This code handles the command that quits the game
if (direction == "quit") or (direction == "exit"):
printNow("Goodbye!")
return exitLoc
