Así, en nuestro ejemplo, podemos hacer que `tags` sea específicamente una "lista de strings":

{* ../../docs_src/body_nested_models/tutorial002_py310.py hl[12] *}

## Tipos de conjunto

Pero luego pensamos en ello, y nos damos cuenta de que los tags no deberían repetirse, probablemente serían strings únicos.

Y Python tiene un tipo de datos especial para conjuntos de elementos únicos, el `set`.

		"client_id":     {c.ClientID},
	}
	if c.RedirectURL != "" {
		v.Set("redirect_uri", c.RedirectURL)
	}
	if len(c.Scopes) > 0 {
		v.Set("scope", strings.Join(c.Scopes, " "))
	}
	v.Set("state", state)
	v.Set("nonce", state)
	if strings.Contains(c.Endpoint.AuthURL, "?") {
		buf.WriteByte('&')
	} else {
		buf.WriteByte('?')
	}
	buf.WriteString(v.Encode())
	return buf.String()
}

	}
	if len(s) == 0 {
		return
	}
	for p := range strings.SplitSeq(s, ",") {
		if p == "" {
			continue
		}
		slc := strings.Split(p, "=")
		if len(slc) != 2 {
			return r, errInvalidReplicateDecisionFormat
		}
		tgtStr := strings.TrimSuffix(strings.TrimPrefix(slc[1], `"`), `"`)
		tgt := strings.Split(tgtStr, ";")
		if len(tgt) != 4 {
			return r, errInvalidReplicateDecisionFormat
