Хубаво е този метод да разчита на нещо случайно. В реален случай никога не цепиш картите точно посредата. Няма да има тестове за това, просто е добре да го направиш.

Не е добра идея да инициализираш нови играчи при всяко извикване на този метод. Още повече, че ако го извикам два пъти, ще направиш повече играчи от необходимото.

Също така, можеш да пропуснеш temp:
self.players.append(Player())

Георги

Раздаването трябва да е наобратно. Вместо да даваш всички карти на един играч, преди да дадеш на следващия, всеки играч трябва да получи толкова карти, колкото е съответния броя в първия елемент на dealing_instructions, после всеки играч да получи от втория елемент и т.н.
