Functionally shuffling a list

There are quite a few questions on stack overflow regarding the random.shuffle method of the random module.

Something that irks me about shuffle is that it shuffles in-place rather than returning a shuffled copy.

Note that shuffle works in place, and returns None.

Therefore expressions like

for index, (parent1, parent2) in enumerate(zip(sorted(population)[::2], shuffle(population)[1::2])):

don't work. Writing it with a side effect seems unnecessarily verbose:

other_half = population[1::2]
random.shuffle(other_half)
for index, (parent1, parent2) in enumerate(zip(sorted(population)[::2], other_half):

What's a pythonic way of functionally shuffling a list?
