Similarly, you cannot redefine a path operation:

{* ../../docs_src/path_params/tutorial003b.py hl[6,11] *}

The first one will always be used since the path matches first.

## Predefined values { #predefined-values }

It will all be combined and included in your OpenAPI, and shown in the API docs:

<img src="/img/tutorial/additional-responses/image01.png">

## Combine predefined responses and custom ones { #combine-predefined-responses-and-custom-ones }

You might want to have some predefined responses that apply to many *path operations*, but you want to combine them with custom responses needed by each *path operation*.

* `skip`, un `int` con un valor por defecto de `0`.
* `limit`, un `int` opcional.

/// tip | Consejo

También podrías usar `Enum`s de la misma manera que con [Parámetros de Path](path-params.md#predefined-values){.internal-link target=_blank}.

* `skip`, `int` зі значенням за замовчуванням `0`.
* `limit`, опціональний `int`.


/// tip | Підказка

Ви також можете використовувати `Enum`-и, так само як і з [Path Parameters](path-params.md#predefined-values){.internal-link target=_blank}.

* `needy`, a required `str`.
* `skip`, an `int` with a default value of `0`.
* `limit`, an optional `int`.

/// tip

You could also use `Enum`s the same way as with [Path Parameters](path-params.md#predefined-values){.internal-link target=_blank}.

## Deployment Concepts { #deployment-concepts }

These examples run the server program (e.g Uvicorn), starting **a single process**, listening on all the IPs (`0.0.0.0`) on a predefined port (e.g. `80`).

This is the basic idea. But you will probably want to take care of some additional things, like:

* Security - HTTPS
* Running on startup
* Restarts

        assertFalse(SmbOperationException.ErrorCode.UNKNOWN_ERROR.isRetryable());
        assertFalse(SmbOperationException.ErrorCode.INTERNAL_ERROR.isRetryable());
    }

    @Test
    @DisplayName("Should test predefined retry policies")
    void testPredefinedRetryPolicies() {
        // DEFAULT policy
        SmbOperationException.RetryPolicy defaultPolicy = SmbOperationException.RetryPolicy.DEFAULT;

         * @return the new reference count after decrementing
         */
        public int decrement() {
            return count.decrementAndGet();
        }
    }

    /**
     * Enumeration of predefined statistics actions that can be recorded
     * during crawler operations. Each action represents a specific event
     * or milestone in the crawling process.
     */
    public enum StatsAction {

For simplicity, here we are just adding the scopes received directly to the token.

But in your application, for security, you should make sure you only add the scopes that the user is actually able to have, or the ones you have predefined.

///

{* ../../docs_src/security/tutorial005_an_py310.py hl[157] *}

## Declare scopes in *path operations* and dependencies { #declare-scopes-in-path-operations-and-dependencies }

* They will be marked with a list of tags that contain a single string `"items"`.
    * These "tags" are especially useful for the automatic interactive documentation systems (using OpenAPI).
* All of them will include the predefined `responses`.
* All these *path operations* will have the list of `dependencies` evaluated/executed before them.
    * If you also declare dependencies in a specific *path operation*, **they will be executed too**.
