Without types, that's almost impossible to achieve.

Notice that the variable `item` is one of the elements in the list `items`.

And still, the editor knows it is a `str`, and provides support for that.

#### Tuple and Set { #tuple-and-set }

You would do the same to declare `tuple`s and `set`s:

///

/// warning | Alertes

Vous pouvez déclarer plusieurs paramètres `File` et `Form` dans un *chemin d'accès*, mais vous ne pouvez pas également déclarer des champs `Body` que vous vous attendez à recevoir en JSON, car la requête aura le corps encodé en `multipart/form-data` au lieu de `application/json`.

  int64_t* dims;
  // The data type. May be 0 to denote unknown type.
  TF_DataType dtype;
};

typedef struct TF_ShapeAndType TF_ShapeAndType;

// A list of TF_ShapeAndType elements..
struct TF_ShapeAndTypeList {
  int num_items;
  TF_ShapeAndType* items;
};
typedef struct TF_ShapeAndTypeList TF_ShapeAndTypeList;

// API for manipulating TF_ShapeAndTypeList objects.
//

        makeMap(createMapMaker().concurrencyLevel(1).initialCapacity(1));
    Segment<Object, Object, ?, ?> segment = map.segments[0];
    assertEquals(1, segment.table.length());

    // manually add elements to avoid expansion
    int originalCount = 1024;
    InternalEntry<Object, Object, ?> entry = null;
    for (int i = 0; i < originalCount; i++) {
      Object key = new Object();
      Object value = new Object();

        makeMap(createMapMaker().concurrencyLevel(1).initialCapacity(1));
    Segment<Object, Object, ?, ?> segment = map.segments[0];
    assertEquals(1, segment.table.length());

    // manually add elements to avoid expansion
    int originalCount = 1024;
    InternalEntry<Object, Object, ?> entry = null;
    for (int i = 0; i < originalCount; i++) {
      Object key = new Object();
      Object value = new Object();

    IdentityHashMap<Entry<K, V>, Boolean> duplicates = null;
    int dupCount = 0;
    for (int entryIndex = n - 1; entryIndex >= 0; entryIndex--) {
      // requireNonNull is safe because the first `n` elements have been filled in.
      Entry<K, V> entry = requireNonNull(entryArray[entryIndex]);
      K key = entry.getKey();
      V value = entry.getValue();
      checkEntryNotNull(key, value);

Pour cela, utilisez le `list` Python standard :

## Réponse avec un `dict` arbitraire { #response-with-arbitrary-dict }

Vous pouvez également déclarer une réponse en utilisant un simple `dict` arbitraire, en déclarant uniquement le type des clés et des valeurs, sans utiliser de modèle Pydantic.
