- [IV](#iv): is a randomly generated initialization vector. It is public and part of the object metadata.
- `context_values`: are values like the bucket and object name and other information which should be cryptographically bound to the KEK.

To summarize for any encrypted object there exists (at least) three different keys:

pkg crypto/x509, type CertificateInvalidError struct, Detail string
pkg crypto/x509, type CertificateRequest struct, URIs []*url.URL
pkg crypto/x509, type VerifyOptions struct, MaxConstraintComparisions int
pkg crypto/x509/pkix, method (Name) String() string
pkg crypto/x509/pkix, method (RDNSequence) String() string
pkg database/sql, func OpenDB(driver.Connector) *DB
pkg database/sql/driver, type Connector interface { Connect, Driver }

这表示：

* 变量 `prices` 是一个 `dict`：
    * 这个 `dict` 的所有键为 `str` 类型（可以看作是字典内每个元素的名称）。
    * 这个 `dict` 的所有值为 `float` 类型（可以看作是字典内每个元素的价格）。

### 类作为类型

你也可以将类声明为变量的类型。

假设你有一个名为 `Person` 的类，拥有 name 属性：

{* ../../docs_src/python_types/tutorial010.py hl[1:3] *}


接下来，你可以将一个变量声明为 `Person` 类型：

{* ../../docs_src/python_types/tutorial010.py hl[6] *}


然后，你将再次获得所有的编辑器支持：

	public final fun expiresAt ()J
	public fun hashCode ()I
	public final fun hostOnly ()Z
	public final fun httpOnly ()Z
	public final fun matches (Lokhttp3/HttpUrl;)Z
	public final fun name ()Ljava/lang/String;
	public final fun newBuilder ()Lokhttp3/Cookie$Builder;
	public static final fun parse (Lokhttp3/HttpUrl;Ljava/lang/String;)Lokhttp3/Cookie;

`cluster/saltbase/salt/kube-dns`, i.e. `cluster/saltbase/salt/kube-dns/{skydns-rc.yaml.base,skydns-rc.yaml.in}`, either substitute one of `__PILLAR__FEDERATIONS__DOMAIN__MAP__` or `{{ pillar['federations_domain_map'] }}` with the corresponding federation name to domain name value or remove them if you do not support cluster federation at this time. If you plan to substitute the parameter with its value, here is an example for `{{ pillar['federations_domain_map'] }}` ([#28132](https://github.com/kubernetes/kubernetes/pull/28132),...
