Please run my code see if it works!

Question

Someone said syntax error, but it works when I run on my device, want to be sure.

NB:
Entering just numbers won't display anything, I intentionally curbed that cos' numbers can't be a name.
Apart from that, alphabets mixed numbers will work or don't enter anything at all.
