Chapter 2
---------

Page 45: In the first sentence of the second paragraph "but not does
not include" should read: "but does not include"

Chapter 3
---------

Page 59: In the second to last paragraph on the page, the fourth
     sentence should have "10 // 3" instead of "10 / 3." 

Page 68: In the third paragraph, "4.8 million" should be "480 million".

Page 75: In discussion question 5, the second sentence should end with
         a "?" instead of "."

Page 76: In programming Exercise 3, "hydrocarbon" should be "carbohydrate."

Chapter 4
---------

page 108: In the second to last sentence on the page "window as not" should be
          "window has not".

Chapter 5
---------

Page 147: Last sentence on page should be "Here is a run of the
     	  change-counting program for Chapter 3.

Chapter 6
---------

Page 185: In Figure 6.7, the arrow from balance should point to the
          square containing 1050.

Chapter 7
---------
page 215: Program fragment at the bottom of the page. The print statement 
     	  should have parentheses: print("No real roots.")

page 216: quadratic5.py This example is not correct for Python 3. The print and
          input statements need modification. It should read:

    # quadratic5.py
    import math 

    def main():
        print ("This program finds the real solutions to a quadratic\n")

        try:
            a, b, c = eval(input("Please enter the coefficients (a, b, c): "))
            discRoot = math.sqrt(b * b - 4 * a * c)
            root1 = (-b + discRoot) / (2 * a)
            root2 = (-b - discRoot) / (2 * a)
            print("\nThe solutions are:", root1, root2)
        except ValueError:
            print("\nNo real roots")
    main()

page 221: Second sentence of the last paragraph of section 7.5.1 "three Boolean 
          expressions" should read "four Boolean expressions".

Chapter 9
---------

page 285: Example interaction at the bottom of the page. All references to
          "rball1" should be just "rball".

page 286: Example interaction at the bottom of the page. All references to
          "rball1" should be just "rball".


Chapter 11
----------

page 375: Footnote at the bottom of the page is missing curly
     braces. "0:<151:>5" should be "{0:<15}{1:>5}".

page 378: True/False Question 8 should be deleted. The comparison function 
     was dropped in Python 3 and is not discussed in the Chapter.

page 379: Discussion question 1. Delete "import string" it's
     unnecessary and not covered in the text.


Chapter 13
----------

page 435: In figure 13.1, all occurrences of "n1" should be "n-1."

Appendix B
----------

Page 480: The interactive example at the bottom of the page is missing
     parentheses in the print statemets. It should be:
     
	>>> print("Hello, World!")
	Hello, World
	>>> print(2+3)
	5
	>>> print("2 + 3 =", 2 + 3)
	2 + 3 = 5
	>>>
