Please, don't quote full posts every time. no need of it and it unnecessarily makes you scroll in order to reach the next post.

I don't know if this is intentional or not, but do you realise that you can have repeating "random" positions (i.e. when you do random.randint(0,2) three times in a row, it's possible to get repeating number(s))?

yes this is the correct code
