The return type doesn't have to be a Pydantic model, it could be a different type, like a list of integers, or a dict, etc.

### When to use `response_model` instead

If the return type is not the same as the type that you want to use to validate, filter, or serialize, use the `response_model` parameter on the decorator instead.

```python

///

## Use `Annotated` in the type for the `q` parameter { #use-annotated-in-the-type-for-the-q-parameter }

Remember I told you before that `Annotated` can be used to add metadata to your parameters in the [Python Types Intro](../python-types.md#type-hints-with-metadata-annotations)?

Now it's the time to use it with FastAPI. 🚀

We had this type annotation:

```Python
q: str | None = None
```

// call Recycle() when the object is no longer needed.
// The recycler should handle nil pointers.
type Recycler interface {
	Recycle()
}

// MSS is a map[string]string that can be serialized.
// It is not very efficient, but it is only used for easy parameter passing.
type MSS map[string]string

// Get returns the value for the given key.
func (m *MSS) Get(key string) string {
	if m == nil {

      Class<? super @NonNull E> type, E... contents) {
    return new MinimalCollection<>(type, true, contents);
  }

  private final E[] contents;
  private final Class<? super @NonNull E> type;
  private final boolean allowNulls;

  // Package-private so that it can be extended.
  MinimalCollection(Class<? super @NonNull E> type, boolean allowNulls, E... contents) {

   * natural ordering. The sorted multisets use {@link Ordering#natural()} as the comparator. This
   * method provides more type-safety than {@link #builder}, as it can be called only for classes
   * that implement {@link Comparable}.
   *
   * <p>Note: the type parameter {@code E} extends {@code Comparable<?>} rather than {@code

## Tip parametresi olan list alanları { #list-fields-with-type-parameter }

Ancak Python’da, iç tipleri olan list’leri (ya da "type parameter" içeren tipleri) tanımlamanın belirli bir yolu vardır:

### Tip parametresiyle bir `list` tanımlayın { #declare-a-list-with-a-type-parameter }

`list`, `dict`, `tuple` gibi type parameter (iç tip) alan tipleri tanımlamak için, iç tipi(leri) köşeli parantezlerle "type parameter" olarak verin: `[` ve `]`

```Python

}

// defaultMaxSize defines the default maximum capacity of the cache.
// Its value is the maximum value of the int64 type, which means that when the cache size is not specified,
// the cache can theoretically store as many elements as possible.
// (1 << 63) - 1 is the maximum value that an int64 type can represent.
const (
	defaultMaxSize = math.MaxInt
	// defaultTTL defines the default time-to-live (TTL) for each cache entry.

		t.Fatalf("failed to found column log_id")
