      <comment>We could probably have a specific element for a dev mailing list for things like CI,
        and maybe even a specific element for the user and scm mailing lists. Then leave the more
        lose structure for any other type of mailing list.</comment>

/// tip | 提示

語法 `{"name", "description"}` 會建立一個包含這兩個值的 `set`。

它等同於 `set(["name", "description"])`。

///

#### 使用 `list` 來代替 `set` { #using-lists-instead-of-sets }

如果你忘了使用 `set` 而用了 `list` 或 `tuple`，FastAPI 仍會把它轉換成 `set`，並能正確運作：
