Chú ý rằng, biến `item` là một trong các phần tử trong danh sách `items`.

Và do vậy, trình soạn thảo biết nó là một `str`, và cung cấp sự hỗ trợ cho nó.

#### Tuple and Set

Bạn sẽ làm điều tương tự để khai báo các `tuple` và  các `set`:

### 2. Create a sample OPA Policy

In another terminal, create a policy that allows root user all access and for all other users denies `PutObject`:

```sh
cat > example.rego <<EOF

        }

        private Set<Artifact> createArtifacts(
                ArtifactFactory artifactFactory,
                Set<Artifact> dependencies,
                String inheritedScope,
                ArtifactFilter dependencyFilter)
                throws InvalidVersionSpecificationException {
            Set<Artifact> projectArtifacts = new HashSet<>();

                Configuration passed to Pydantic to define if the response data
                should have all the fields, including the ones that were not set and
                have their default values. This is different from
                `response_model_exclude_defaults` in that if the fields are set,
                they will be included in the response, even if the value is the same
                as the default.
