Looks neat but I gave up on it converging on my new laptop. I'm going to port it to rebol2. This bit confuses me: random.choice(range(0, i) + range(i+1, 4))

Looks neat but I gave up on it converging on my new laptop. I'm going to port it to rebol2. This bit confuses me: random.choice(range(0, i) + range(i+1, 4)) how is that different from random.choice(range(0, 4))? Obviously no Pythonista, but playing around in the REPL I see no diff.
