Ако просто върнеш self.players пак изпълняваш условието ;) Все пак random_player може да е нула, което е частен, но валиден случай. Условието казва "произволен играч", защото няма как да дефинирам нищо конкретно без да ти казвам как да си пазиш играчите.

А защо не просто self.deck.cards.extend(player.get_cards())? Ако се опасяваш, че ще получиш референция към елемента и искаш да го копираш, просто добави [:] отзад и готово.
