Hey Tutors I saw a lot of responses...After analyze them I have resumed two approaches
1.- Generate a random number from 0 to 99999999 and fill this number with zeros (Almost everyone's approach) 2.- Generate 8 random numbers and join them (Pietro and someone else) Which one of this is more randomic? I mean which one of these has lower chances to get duplicates? Until now I'm using approach number 2.......Unless anyone has something against it... Please, let me know what do you think about them Thanks to all for the tremendous help (at least it is tremendous for me) Alberto _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
