I'm still doing practice problems. I haven't heard from the library on any of the books I have requested.
http://www.practicepython.org/exercise/2014/04/16/11-check-primality-functions.html This is not a hard problem, but it got me to thinking a little. A prime number will divide by one and itself. When setting up this loop, if I start at 2 instead of 1, that automatically excludes one of the factors. Then, by default, Python goes "to" the chosen count and not "through" the count, so just the syntax causes Python to rule out the other factor (the number itself). So this works: while True: a=random.randrange(1,8) print (a) for x in range(2,a): if a%x==0: print ("Number is not prime") break wait = input (" "*40 + "Wait") But, what this instructions want printed is "This is a prime number" So how to I use this code logic NOT print (not prime) and have the logic print "This number is prime" -- https://mail.python.org/mailman/listinfo/python-list
