It would help if you told us what result you get, what result you 
expected, and what you don't understand about it.

My guess is that you expected it to print:

2
2
3
2
3
4
2
3
4
5
...

but instead it prints:

2
3
3
4
4
4
5
5
5
5
...

Hint: you are print n each time, not x. n doesn't vary inside the inner 
loop, only in the outer loop.

To understand what is going on better, it might help if you run this 
instead:


for n in range(3, 20):
     for x in range(2, n):
         print('n = %d, x = %d' % (n, x))
