注意，变量 `item` 是列表 `items` 中的元素之一。

而且，编辑器仍然知道它是一个 `str`，并为此提供了支持。

#### 元组和集合

声明 `tuple` 和 `set` 的方法也是一样的：

{* ../../docs_src/python_types/tutorial007.py hl[1,4] *}


这表示：

* 变量 `items_t` 是一个 `tuple`，其中的前两个元素都是 `int` 类型, 最后一个元素是 `str` 类型。
* 变量 `items_s` 是一个 `set`，其中的每个元素都是 `bytes` 类型。

#### 字典

定义 `dict` 时，需要传入两个子类型，用逗号进行分隔。

第一个子类型声明 `dict` 的所有键。

    /** Map from method name to array of {@link MethodDesc} */
    protected final Map<String, MethodDesc[]> methodDescsCache = newHashMap();

    /** Set of invalid property names */
    protected final Set<String> invalidPropertyNames = newHashSet();

    /**
     * Creates a {@link BeanDescImpl}.
     *
     * @param beanClass
     *            the class of the bean. Must not be {@literal null}

It is easy to assume that HTTPS is something that is just "enabled" or not.

But it is way more complex than that.
