I would also prefer a `random.shuffled` function. The reason I didn't propose it is because there's usually more resistance for adding new functions. But in my view that'll be the best solution.

I agree that calling random.shuffle imperatively is annoying. But I don't think your proposed solution is readable. You're not taking a sample. A sample generally implies a strict subset, usually quite a small one.
I've often thought there should just be a `random.shuffled()` function which returns a shuffled copy, similar to `.sort()` and `sorted()` or `.reverse()` and `reversed()`.

When writing some code now, I needed to produce a shuffled version of `range(10, 10 ** 5)`.
This is one way to do it:
shuffled_numbers = list(range(10, 10 ** 5)) random.shuffle(shuffled_numbers)
I don't like it because (1) it's too imperative and (2) I'm calling the list "shuffled" even before it's shuffled.
Another solution is this:
shuffled_numbers = random.sample(range(10, 10 ** 5), k=len(range(10, 10 ** 5)))
This is better because it solves the 2 points above. However, it is quite cumbersome.
I notice that the `random.sample` function doesn't have a default behavior set when you don't specify `k`. This is fortunate, because we could make that behavior just automatically take the length of the first argument. So we could do this:
shuffled_numbers = random.sample(range(10, 10 ** 5))
What do you think?
