Section 2.2.2; the second while loop doesn't increment the counter variable a. The listing should be:

>>> a = 0
>>> while a < 6:
...   print a
...   if a >= 2:
...     break
...   a += 1
... else:
...   print 'Loop terminated normally'

Section 4.3.2, footnote 6; this states that .NET will use System.Text.Encoding.Default automatically. This isn't true. As the page itself notes .NET will use UTF-8 when you don't specify an encoding. Encoding.Default is an encoding representing the ANSI code page of the system. On a UK English Windows machine this will actually be the the windows-1252 encoding and not ISO-8859-1 as the footnote states. Codepage 1252 is a superset of ISO-8859-1.
