Você pode declarar o tipo de um parâmetro na função usando as anotações padrões do Python:

{* ../../docs_src/path_params/tutorial002.py hl[7] *}

Nesse caso, `item_id` está sendo declarado como um `int`.

/// check | Verifique



///

	Isso vai dar à você suporte do seu editor dentro das funções, com verificações de erros, autocompletar, etc.

     * Get associated memory region
     *
     * @return memory region for this request

    }

    /**
     * Check if request is completed
     *
     * @return true if completed, false otherwise
     */
    public boolean isCompleted() {
        return completed;
    }

    /**
     * Mark request as completed
     */

## Die Instanz als Abhängigkeit verwenden

Dann könnten wir diesen `checker` in einem `Depends(checker)` anstelle von `Depends(FixedContentQueryChecker)` verwenden, da die Abhängigkeit die Instanz `checker` und nicht die Klasse selbst ist.

Und beim Auflösen der Abhängigkeit ruft **FastAPI** diesen `checker` wie folgt auf:

```Python
checker(q="somequery")
```

	config.Lock()
	defer config.Unlock()

	// check if tier name is in all caps
	tierName := tier.Name
	if tierName != strings.ToUpper(tierName) {
		return errTierNameNotUppercase
	}

	// check if tier name already in use
	if _, exists := config.isTierNameInUse(tierName); exists {
		return errTierAlreadyExists
	}

                    && field.getType() == String.class && !field.getName().equals("serialVersionUID")) {

                // Check field name follows convention
                assertTrue("Field name should match pattern: " + field.getName(), labelPattern.matcher(field.getName()).matches());

                // Check field value follows convention
                field.setAccessible(true);
                String value = (String) field.get(null);

        }

        override fun nanoTime() = nanoTime

        override fun coordinatorNotify(taskRunner: TaskRunner) {
          taskRunner.assertLockHeld()
          check(waitingCoordinatorTask != null)

          // Queue a task to resume the waiting coordinator.
          serialTaskQueue +=
            object : SerialTask {
              override fun start() {

In your top-level application, `app`, mount the sub-application, `subapi`.

In this case, it will be mounted at the path `/subapi`:

{* ../../docs_src/sub_applications/tutorial001.py hl[11, 19] *}

### Check the automatic API docs { #check-the-automatic-api-docs }

Now, run the `fastapi` command with your file:

<div class="termy">

```console
$ fastapi dev main.py
