In the castle game, the player must answer a riddle correctly or provide a password in order to pass through to the Courtyard. Add that to your game.

Question

Note: The answer will need to include a new file-level variable, a change to the showGate function (to prompt the riddle/password) and a change to the pickRoom function (to allow for the riddle/password answer).

Answer 1

```
#variable to track if the riddle has been answered
riddleAnswered = false
#This method prints the description for the Gate
def showGate ():
printNow("You are at the castle gate.")
printNow("You feel a sense of dread.")

if not riddleAnswered:
printNow("The gate is shut tight. A skull at the gate's top ")
printNow(" looks down upon you. In a shrill voice it says: ")
printNow(" \"This thing all things devours\"")
printNow(" \"Birds, beasts, trees, flowers\"")
printNow(" \"Gnaws iron, bits steel\"")
printNow(" \"Grings hard stones to meal\"")
printNow(" \"Slays king, ruins town, \"")
printNow(" \"And beats mountain down.\"")
printNow(" \"What am I?\"")
else:
printNow("You can see a courtyard to the north")
printNow("The drawbridge is behind you to the south.")
#This method actually parses user directions to determine what changes should occur
def pickRoom(direction , room):
global riddleAnswered
#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!")
