Vamos tentar isso em um exemplo com tags para `users` e `items`.

Crie metadados para suas tags e passe-os para o parâmetro `openapi_tags`:

Observe que você pode usar Markdown dentro das descrições. Por exemplo, "login" será exibido em negrito (**login**) e "fancy" será exibido em itálico (_fancy_).

Ao fazer isso, seu editor pode fornecer suporte mesmo durante o processamento de itens da lista:

Sem tipos, isso é quase impossível de alcançar.

Observe que a variável `item` é um dos elementos da lista `items`.

E, ainda assim, o editor sabe que é um `str` e fornece suporte para isso.
