Of course you can assign the result slice to b. You just have to do it the
right way. 

You keep getting None because you do it the wrong way. Unfortunately you
aren't showing us your code, so we have no idea what you are doing wrong.
My guess is that you are doing something like this:

a = [1, 2, 3, 4, 5, 6, 7, 8]
b = random.shuffle(a)[0:3]

That's wrong -- shuffle() modifies the list you pass, and returns None. You
cannot take a slice of None. Try this:

a = [1, 2, 3, 4, 5, 6, 7, 8]
b = a[0:3]

“Cheer up,” they said, “things could be worse.” So I cheered up, and sure
enough, things got worse.
