有些类型可以在方括号中接收“类型参数”（type parameters），用于声明其内部值的类型。比如“字符串列表”可以写为 `list[str]`。

这些能接收类型参数的类型称为“泛型类型”（Generic types）或“泛型”（Generics）。

你可以把相同的内建类型作为泛型使用（带方括号和内部类型）：

* `list`
* `tuple`
* `set`
* `dict`

#### 列表 { #list }

例如，我们来定义一个由 `str` 组成的 `list` 变量。

用同样的冒号（`:`）语法声明变量。

类型写 `list`。

因为 list 是一种包含内部类型的类型，把内部类型写在方括号里：

   * Splits {@code sequence} into string components and returns them as an immutable list. If you
   * want an {@link Iterable} which may be lazily evaluated, use {@link #split(CharSequence)}.
   *
   * @param sequence the sequence of characters to split
   * @return an immutable list of the segments split from the parameter
   * @since 15.0
   */
  public List<String> splitToList(CharSequence sequence) {
    checkNotNull(sequence);

Indem Sie nur `BackgroundTasks` (und nicht `BackgroundTask`) verwenden, ist es dann möglich, es als *Pfadoperation-Funktion*-Parameter zu verwenden und **FastAPI** den Rest für Sie erledigen zu lassen, genau wie bei der direkten Verwendung des `Request`-Objekts.
