Но вы также хотите, чтобы она принимала новые элементы. И если элементы ранее не существовали, она создаёт их и возвращает HTTP статус-код 201 «Created».

Чтобы добиться этого, импортируйте `JSONResponse` и верните туда свой контент напрямую, установив нужный вам `status_code`:

{* ../../docs_src/additional_status_codes/tutorial001_an_py310.py hl[4,25] *}

  /**
   * Invoked on a background thread after the referent has been garbage collected unless security
   * restrictions prevented starting a background thread, in which case this method is invoked when
   * new references are created.
   */
  void finalizeReferent();

/** Never actually created; instead delegates to JdkBackedImmutableMultiset. */
final class RegularImmutableMultiset<E> extends ImmutableMultiset<E> {
  static final ImmutableMultiset<Object> EMPTY =
      JdkBackedImmutableMultiset.create(ImmutableList.of());

  "component": {
    "group": "${pom.groupId}",
    "module": "${pom.artifactId}",
    "version": "${pom.version}",
    "attributes": {
      "org.gradle.status": "${module.status}"
    }
  },
  "createdBy": {
    "maven": {
      "version": "${maven.version}",
      "buildId": "${maven.build.version}"
    }
  },
  "variants": [
    {
      "name": "${variant.jvmEnvironmentVariantName}ApiElements",

                "flags should be DCERPC_FIRST_FRAG | DCERPC_LAST_FRAG");

        // Although we cannot directly assert that super(handle) was called with Mockito for a constructor,
        // the fact that the object is successfully created and its inherited fields are accessible
        // implies the super constructor was invoked.
    }

Pero también quieres que acepte nuevos elementos. Y cuando los elementos no existían antes, los crea y devuelve un código de estado HTTP de 201 "Created".

Para lograr eso, importa `JSONResponse`, y devuelve tu contenido allí directamente, configurando el `status_code` que deseas:

{* ../../docs_src/additional_status_codes/tutorial001_an_py310.py hl[4,25] *}

    subprocess.run(["git", "push", "origin", branch_name], check=True)
    logging.info("Creating PR")
    pr = r.create_pull(title=message, body=message, base="master", head=branch_name)
    logging.info(f"Created PR: {pr.number}")
    logging.info("Finished")
