Somewhat feebly, if you don't mind my saying so, but don't worry. The usual way to proceed in the face of such ignorance is to insert some form of output that will tell you the answer to your question. So: >>> for n in range(2, 20): ... print range(2, n) ... for x in range(2, n): ... if n % x == 0: ... print n, 'equals', x, '*', n/x ... break ... else: ... print n, "is prime" ... [] 2 is prime [2] 3 is prime [2, 3] 4 equals 2 * 2 [2, 3, 4] 5 is prime [2, 3, 4, 5] 6 equals 2 * 3 [2, 3, 4, 5, 6] 7 is prime [2, 3, 4, 5, 6, 7] 8 equals 2 * 4 [2, 3, 4, 5, 6, 7, 8] 9 equals 3 * 3 and so on! This is the value of the interactive interpreter. regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 Holden Web LLC http://www.holdenweb.com/ -- http://mail.python.org/mailman/listinfo/python-list
