3. This myro function returns 0 or 1 value(s) ‏based upon obstacles behind the robot. Robot for $200 getIR()‏

4. Motors(-1,1) causes the robot to do this. Spin counter- clockwise (left). Robot for $400

5. Range of possible values returned by the getObstacle() function. 0 to 7000 Robot for $600

6. The dimensions of the picture returned by the takePicture() function. Robot for $800 256 (X) by 192 (Y)‏

7. Difference between the getLight() and getBright() functions. Robot for $1000 getLight() returns values from sensors on robot, getBright() returns sum of pixel values from fluke camera.

8. What is the values of: ( (14 >= 0) or (4 != 3) ) True? for $200 True

9. All recursive functions have these 2 parts: a base (terminating) case, and a recursive call. True? for $400 False

10. getIR(“left”) and (5 % 2 == 3) True? for $600 False

11. for i in range(5,3,-1): if (i % 2 == 0): return True else: return False False True? for $800

12. ( (5 > 4) or (10 >= 10) ) or (not (5 / 4 == 1)) True True? for $1000

13. What this program prints: for i in range(10): print i + 1 Numbers 1 through 10, one per line. Programs for $200

14. x = 5 while (x > 0): print x x = x-1 Programs for $400 Numbers 5 to 1, one per line

15. Write this using a while loop: for i in range(5,10,2): print i Programs for $600 x = 5 while ( x < 10): print x x = x+2

16. Result of mystery(2,3): def mystery(a,b): if (a == 0): return b else: return mystery(a-1, b+1)‏ 5 Programs for $800

17. What the mystery function does: def mystery(a,b): if (a == 0): return b else: return mystery(a-1, b+1)‏ Programs for $1000 Sum a and b.

18. Five immutable data types. Data types for $200 int, float, string, bool, tuple

19. myList = [True,34, [5,6],”test”] An expression that accesses the number six (6) from the list(s) above. Data types for $400 myList[2][1]

20. How to change myStr = “Jay” To myStr = “jay” Data types for $600 myStr = ‘j’ + myStr[1:]

21. A = [5,6,7,8] B = A B[3] = B[2]+3 The value of A[3] 10 Data types for $800

22. r = “Python is Great!” The result of: r[2]+r[12]+r[8]+r[14]+r[15] Data types for $1000 test!

23. This return value means that a function did not return a specific value. Potpourri for $200 None, (of type NoneType)

24. These are the three types of sensors on the Lancet Fluke. Potpourri for $400 IR Obstacle sensors (getObstacle), the camera (takePicture, getBright), and the battery voltage (getBattery) sensor.

25. Arithmetic operators (like +, -, *, /) have _____ precedence than logical operators (like or, and, not) so arithmetic is done _____. Potpourri for $600 Higher/greater, first

26. Rewrite the following code using a for loop. x = 7 while (x > 3): print x x = x -1 for x in range(7,3,-1): print x Potpourri for $800

27. This is the sorting algorithm that Donald Knuth credits John von Neumann with inventing. Potpourri for $1000 Merge Sort
