### 現代的なPythonのみ { #just-modern-python }

すべて標準の **Python の型** 宣言（Pydantic に感謝）に基づいています。新しい構文を学ぶ必要はありません。標準的でモダンな Python だけです。

（FastAPI を使わない場合でも）Python の型の使い方を 2 分で復習したい場合は、短いチュートリアル [Python の型](python-types.md) を参照してください。

型を使った標準的な Python を記述します:

   *       <ul>
   *         <li>UNSET, meaning "null pointer"
   *         <li>one plus an index into the entries and elements array
   *       </ul>
   *   <li>another java.util.Set delegate implementation. In most modern JDKs, normal java.util hash
   *       collections intelligently fall back to a binary search tree if hash table collisions are
   *       detected. Rather than going to all the trouble of reimplementing this ourselves, we

MySQL veya PostgreSQL gibi ilişkisel veritabanlarıyla nispeten sıkı bağlıdır, bu nedenle Couchbase, MongoDB, Cassandra vb. gibi bir NoSQL veritabanını ana depolama motoru olarak kullanmak pek kolay değildir.

### 그저 현대 파이썬 { #just-modern-python }

(Pydantic 덕분에) 모든 것이 표준 **Python 타입** 선언을 기반으로 합니다. 새로 배울 문법이 없습니다. 그저 표준적인 현대 파이썬입니다.

Python 타입을 어떻게 사용하는지 2분 정도 복습이 필요하다면(FastAPI를 사용하지 않더라도), 다음의 짧은 자습서를 확인하세요: [Python 타입](python-types.md).

"_If you're looking to learn one **modern framework** for building REST APIs, check out **FastAPI** [...] It's fast, easy to use and easy to learn [...]_"

"_We've switched over to **FastAPI** for our **APIs** [...] I think you'll like it [...]_"

     * @deprecated This method originally used internal JDK APIs (sun.misc.SharedSecrets) for
     *             performance optimization, but those APIs have been removed for safety and
     *             compatibility with modern Java versions. This method now simply calls
     *             {@code new String(chars)}, providing no additional value.
     *             Use the {@link String#String(char[])} constructor directly instead.

### Mémoire par processus { #memory-per-process }

Maintenant, lorsque le programme charge des choses en mémoire, par exemple, un modèle de machine learning dans une variable, ou le contenu d'un gros fichier dans une variable, tout cela **consomme une partie de la mémoire (RAM)** du serveur.

Adopter temporairement ce point de vue (celui de la *personne développeuse externe*) peut vous aider à trouver plus évident où placer les paramètres, le modèle Pydantic pour le corps, pour la réponse, etc., pour cette *API externe*.

### Créer un `APIRouter` de callback { #create-a-callback-apirouter }

### Modelleri Oluşturma { #create-models }

`SQLModel`’i import edin ve bir veritabanı modeli oluşturun:

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[1:11] hl[7:11] *}

`Hero` sınıfı, bir Pydantic modeline çok benzer (hatta altta aslında *bir Pydantic modelidir*).
