• This quiz is SOLO.
• This portion is worth 100 pts.  There is no written portion this week.
• No notes, books, web sites (except reading this quiz and accessing Autolab).
• IDLE hint:  python -m idlelib.idle &
• Autolab hint (to submit):  http://autolab.cs.cmu.edu/
• You must submit your quiz8.py file to Autolab before leaving the lab!  You will not have access to this file after you leave the lab!
• To start, download this one file: quiz8.py (elided).  This contains full implementations of Tetris and Snake.  You should edit and submit that same file with the changes required by the exercises below.
• Good luck! :-)

1. Tetris Space-Fall [30 pts]
   In Tetris, make it so that hitting the spacebar makes the current piece fall all the way to the bottom (without animating, it just goes directly to its final resting position) and starts a new piece immediately falling (and ending the game if a new falling piece cannot be legally placed).
    
2. Tetris Special-Z [30 pts]
   In Tetris, make it so that if the user hits 'z' at any time, then whenever the next falling piece is selected (at some future time), it will be a z-piece.  ALSO... This is the ONLY time a z piece will be selected.  (So a z piece will never be randomly selected.)
    
3. Snake Immortality [40 pts]
   In Snake, make it so that if the snake would die for any reason, instead the move does not occur, giving the appearance that the snake is just paused waiting for a legal move to be entered, at which point play resumes normally.
