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.)
