Ако ти трябва конкретен елемент ор модул, импортирай само него (from random import shuffle). Ако не знаеш какво ти трябва, импортирай целият модул (import random), след което си използвай конкретен обект, префиксирайски с модула (random.shufle(something)).
Още не сме говорили за модули, но да импортираш със звезда е антипатърн, защото рискуваш конфликт на имена.

self.all_cards = self.all_cards[random_length:] + self.all_cards[:random_length] прави същото.
Забележи, че нулата е ненужна. Слайсването така или иначе започва от нула и приключва с последния елемент.

Обърка ме с двете променливи за карти, но съм почти сигурен, че това, което връщаш тук, не е един елемент от клас Deck, както е по условие, а просто списък с карти.
