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()`.
