Developer’s solution

# Создаем пустой список для первого списка продуктов
spisok1 = []
# Читаем продукты из первого списка до слова "стоп"
while True:
    produkt = input()
    if produkt == "стоп":
        break
    spisok1.append(produkt)

# Создаем пустой список для второго списка продуктов
spisok2 = []
# Читаем продукты из второго списка до слова "стоп"
while True:
    produkt = input()
    if produkt == "стоп":
        break
    spisok2.append(produkt)

# Объединяем два списка
obshiy_spisok = spisok1 + spisok2

# Удаляем дубликаты, преобразовав список во множество (set) и обратно в список
obshiy_spisok = list(set(obshiy_spisok))

# Сортируем список по алфавиту
obshiy_spisok.sort()

# Выводим отсортированный список
for produkt in obshiy_spisok:
    print(produkt)
