## Tipo "set"


Mas então, quando nós pensamos mais, percebemos que as tags não devem se repetir, elas provavelmente devem ser strings únicas.

E que o Python tem um tipo de dados especial para conjuntos de itens únicos, o `set`.

Então podemos importar `Set` e declarar `tags` como um `set` de `str`s:


```Python hl_lines="1  14"

message NonResourcePolicyRule {
  // `verbs` is a list of matching verbs and may not be empty.
  // "*" matches all verbs. If it is present, it must be the only entry.
  // +listType=set
  // Required.
  repeated string verbs = 1;

  // `nonResourceURLs` is a set of url prefixes that a user should have access to and may not be empty.
  // For example:
  //   - "/healthz" is legal
  //   - "/hea*" is illegal
