## Типы множеств

Но затем мы подумали и поняли, что теги не должны повторяться и, вероятно, они должны быть уникальными строками.

И в Python есть специальный тип данных для множеств уникальных элементов - `set`.

Тогда мы можем обьявить поле `tags` как множество строк:

{* ../../docs_src/body_nested_models/tutorial003_py310.py hl[12] *}

            testBlock.prepare(nextRequest);
        }

        @Test
        @DisplayName("Test set request credits")
        void testSetRequestCredits() {
            testBlock.setRequestCredits(10);
        }
