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: in the third line, "x2 >= x3" should read "x1 >= x3".

          "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 345: In the second code fragment on the page, the input should be
     converted to a number both places:

     nums = []
     x = eval(input("Enter a number: "))
     while x >= 0:
     	   nums.append(x)
	   x = eval(input("Enter a number: "))		

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.

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
	>>>
