# Задачи - реализовать нативную работу с объектами:
# 1. Вывод колоды в терминал:
print(deck)  # вместо print(deck.show())

card1, card2 = deck.draw(2)
# 2. Вывод карты в терминал:
print(card1, card2)  # вместо print(card1.to_str())

# 3. Сравнение карт:
if card2 > card1:
    print(f"{card2} больше {card1}")

# 4. Итерация по колоде:
# for card in deck:
#     print(card)
print(min(deck))

# Просмотр карты в колоде по ее индексу:
print(deck)
print(deck[0])
