for n in range(2, 100): #'n' is the number we're checking for x in range(2, n): #'x' is going to be each number up to our current 'n' if n % x == 0: #checking our number against all numbers so far to see if it eveny divides print n, 'equals', x, '*', n/x break else: # loop fell through without finding a factor, therefore it is prime print n, 'is a prime number'
