Summary: Example function # 4.4 is incorrect

Initial Comment:
(Refers to the online tutorial at 
http://www.python.org/doc/current/tut/node6.html#SECTIO
N006400000000000000000)

The code should be changed to:

>>> for n in range(2, 10):
...     for x in range(2, n):
...         if n % x == 0:
...             print n, 'equals', x, '*', n/x
...             break 
...         elif x < (n-1) :
...             continue # keep checking
...         else:
...             print n, 'is a prime number'



Otherwise, you will get multiple "7 is a prime number" 
statements with the current code. Also, if would 
incorrectly say "9 is a prime number" and "9 equals 3 
* 3". I added the elif/continue part to take care of 
these two problems.

I'll add a comment to the "else" clause of the for loop in  a future checkin, but the code is correct.

(The submitter admitted he made an indentation error in a followup email.)
