### Your task

Translate an English text – the original content – to a target language.

def test_create_item(client: TestClient):
    item_data = {

	entry.API.Status = opts.Status
	entry.Tags = make(map[string]any, len(opts.Tags))
	for k, v := range opts.Tags {
		entry.Tags[k] = v
	}

	// Merge tag information if found - this is currently needed for tags
	// set during decommissioning.
	if reqInfo := logger.GetReqInfo(ctx); reqInfo != nil {
		reqInfo.PopulateTagsMap(opts.Tags)
	}
	ctx = logger.SetAuditEntry(ctx, &entry)

                            },
                            "tax": {"title": "Tax", "type": "number", "default": 10.5},
                            "tags": {
                                "title": "Tags",
                                "type": "array",
                                "items": {"type": "string"},
                                "default": [],
                            },

So, in our example, we can make `tags` be specifically a "list of strings":

{* ../../docs_src/body_nested_models/tutorial002_py310.py hl[12] *}

## Set types { #set-types }

But then we think about it, and realize that tags shouldn't repeat, they would probably be unique strings.

And Python has a special data type for sets of unique items, the `set`.

Then we can declare `tags` as a set of strings:

        then:
        format(result.docbook) == '''<para><UNHANDLED-ELEMENT>&lt;unknown&gt;text&lt;/unknown&gt;</UNHANDLED-ELEMENT><UNHANDLED-ELEMENT>&lt;inheritdoc&gt;<UNHANDLED-TAG>{@unknown text}</UNHANDLED-TAG><UNHANDLED-TAG>{@p text}</UNHANDLED-TAG><UNHANDLED-TAG>{@ unknown}</UNHANDLED-TAG>&lt;/inheritdoc&gt;</UNHANDLED-ELEMENT></para>'''
    }

    def handlesMissingStartTags() {
        _ * classMetaData.rawCommentText >> 'a para</b></p>'

	GOPATH = ""

	// GOROOT - GOROOT value at the time of build.
	GOROOT = ""

	// Version - version time.RFC3339.
	Version = "DEVELOPMENT.GOGET"

	// ReleaseTag - release tag in TAG.%Y-%m-%dT%H-%M-%SZ.
	ReleaseTag = "DEVELOPMENT.GOGET"

	// CommitID - latest commit id.
	CommitID = "DEVELOPMENT.GOGET"

	// ShortCommitID - first 12 characters from CommitID.
	ShortCommitID = "DEVELOPMENT.GOGET"
