这将使 `tags` 成为一个由元素组成的列表。不过它没有声明每个元素的类型。

## 具有子类型的 List 字段

但是 Python 有一种特定的方法来声明具有子类型的列表：

### 从 typing 导入 `List`

首先，从 Python 的标准库 `typing` 模块中导入 `List`：

```Python hl_lines="1"

	// Validates if Versioning with no excluded prefixes omits
	// ExcludedPrefixes tags
	v := Versioning{
		Status: Enabled,
	}
	buf, err := xml.Marshal(v)
	if err != nil {
		t.Fatalf("Failed to marshal %v: %v", v, err)
	}

	str := string(buf)
	if strings.Contains(str, "ExcludedPrefixes") {
		t.Fatalf("XML shouldn't contain ExcludedPrefixes tag - %s", str)
	}
}

func TestVersioningZero(t *testing.T) {

    assertThat(CertificateAdapters.extension.fromDer(bytes))
      .isEqualTo(extension)
  }

  /** Tags larger than 30 are a special case. */
  @Test fun `large tag`() {
    val bytes = "df83fb6800".decodeHex()

    val adapter = Adapters.NULL.withTag(tagClass = DerHeader.TAG_CLASS_PRIVATE, tag = 65_000L)
    assertThat(adapter.toDer(null)).isEqualTo(bytes)
    assertThat(adapter.fromDer(bytes)).isNull()
  }

                A list of tags used by OpenAPI, these are the same `tags` you can set
                in the *path operations*, like:

                * `@app.get("/items/", tags=["items"])`
