This wouldn't really be random. It would ensure that the same number
doesn't come up two times in a row, but that's not random.
According to m-w.com random (as an adjective, which is how we're using it)
is "being or relating to a set or to an element of a set each of whose
elements has equal probability of occurrence"
The key words here being "equal probability of occurrence". By putting that
number in a list you make that numbers chance of beign used 0. Therefore
the next number is no longer random.
I'm not saying that your solution isn't what this person needs but the
number isn't completely random. Just like Jim McAtee said you have the
chance of one number coming up ten, a hundred, even a thousand times in a
row. Is it likely that will happen? No, but it could. The smaller the set
of numbers to choose from the more likely that is to happen. It's the same
as you were taught in school when you learned averages. Just because you
flip a quarter 100 times doesn't mean you'll get 50 heads and 50 tails. Try
it.
