Random numbers from set Python [duplicate]

set_a = {1, 2, 3, 4, 5, 6, 7, 8}

I want to have 4 packages with 2 numbers randomly taken from set_a. Condition is that if a number is chosen, it cannot be taken anymore.

a = [1, 2]
b = [3, 4]
c = [5, 6]
d = [7, 8]

I tried to achieve my goal with random.sample and list comparison but it didn't work out for me.

Next try was to remove the numbers from set with set_a.discard() and set_a.remove() which already have been chosen, but this didn't work either.
