```
./bin/spark-submit --class org.apache.spark.examples.SparkPi \
    --master yarn-client \
    --num-executors 1 \
    --driver-memory 512m \

The job should produce an output as shown below. Note the value of pi in the output.

With `Form` you can declare the same configurations as with `Body` (and `Query`, `Path`, `Cookie`), including validation, examples, an alias (e.g. `user-name` instead of `username`), etc.

/// info

`Form` is a class that inherits directly from `Body`.

///

/// tip

### Applications multiples { #multiple-applications }

Sur le même serveur (ou les mêmes serveurs), il pourrait y avoir **plusieurs applications**, par exemple d'autres programmes d'API ou une base de données.

## Integrated middlewares { #integrated-middlewares }

**FastAPI** includes several middlewares for common use cases, we'll see next how to use them.

/// note | Technical Details

For the next examples, you could also use `from starlette.middleware.something import SomethingMiddleware`.

### Docs for tests

Most of the tests actually run against the example source files in the documentation.

This helps to make sure that:

* The documentation is up-to-date.
* The documentation examples can be run as is.
* Most of the features are covered by the documentation, ensured by test coverage.

#### Apps and docs at the same time

If you run the examples with, e.g.:

<div class="termy">

```console

# o isCheckProcedureDiff: (NotRequired - Default false)
# o loadDataReverseMap: (NotRequired - Default map:{})
# o schemaSyncCheckMap: (NotRequired - Default map:{})
# o propertiesHtmlMap: (NotRequired - Default map:{})
#
# Example:
# map:{
#     ; documentOutputDirectory = ./output/doc
#     ; aliasDelimiterInDbComment = :
#     ; isDbCommentOnAliasBasis = true
#     ; isEntityJavaDocDbCommentValid = true
#     ; isEntityDBMetaDbCommentValid = true

- Never change quotes inside inline code, code blocks, URLs, or file paths.

### Ellipsis

- Keep ellipsis style consistent with existing Korean docs (often `...`).
- Never change `...` in code, URLs, or CLI examples.

### Preferred translations / glossary

Use the following preferred translations when they apply in documentation prose:

- request (HTTP): 요청
- response (HTTP): 응답
- path operation: 경로 처리

Utilisez maintenant l'opération `GET` avec le chemin `/users/me`.

Vous obtiendrez les données de votre utilisateur, par exemple :

```JSON
{
  "username": "johndoe",
  "email": "johndoe@example.com",
  "full_name": "John Doe",
  "disabled": false,
  "hashed_password": "fakehashedsecret"
}
```

### Exécuter le serveur { #run-the-server }

Ensuite, vous exécutez le serveur en passant les configurations comme variables d'environnement ; par exemple, vous pouvez définir un `ADMIN_EMAIL` et `APP_NAME` avec :

<div class="termy">

```console
$ ADMIN_EMAIL="deadpool@example.com" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

   * Returns the maximal range {@linkplain #encloses enclosed} by both this range and {@code
   * connectedRange}, if such a range exists.
   *
   * <p>For example, the intersection of {@code [1..5]} and {@code (3..7)} is {@code (3..5]}. The
   * resulting range may be empty; for example, {@code [1..5)} intersected with {@code [5..7)}
   * yields the empty range {@code [5..5)}.
