## Details

The first `"/static"` refers to the sub-path this "sub-application" will be "mounted" on. So, any path that starts with `"/static"` will be handled by it.

The `directory="static"` refers to the name of the directory that contains your static files.

The `name="static"` gives it a name that can be used internally by **FastAPI**.

* La variable `items_s` es un `set` y cada uno de sus ítems es de tipo `bytes`.

#### Diccionarios (Dicts)

Para definir un `dict` le pasas 2 sub-tipos separados por comas.

El primer sub-tipo es para los keys del `dict`.

El segundo sub-tipo es para los valores del `dict`:

```Python hl_lines="1  4"
{!../../docs_src/python_types/tutorial008.py!}
```

Esto significa:

{{- $statements_length := len .statements -}}
{{- $statements_length := sub $statements_length 1 -}}
{
  "Version": "2012-10-17",
  "Statement": [
{{- range $i, $statement := .statements }}
    {
      "Effect": "{{ $statement.effect | default "Allow" }}",
      "Action": [
"{{ $statement.actions | join "\",\n\"" }}"
      ]{{ if $statement.resources }},
      "Resource": [
