## Technical Details { #technical-details }

The class `BackgroundTasks` comes directly from [`starlette.background`](https://www.starlette.dev/background/).

It is imported/included directly into FastAPI so that you can import it from `fastapi` and avoid accidentally importing the alternative `BackgroundTask` (without the `s` at the end) from `starlette.background`.

 * double myMedian = median().compute(myDataset);
 * }
 *
 * where {@link #median()} has been statically imported.
 *
 * <p>To compute the 99th percentile:
 *
 * {@snippet :
 * double myPercentile99 = percentiles().index(99).compute(myDataset);
 * }
 *
 * where {@link #percentiles()} has been statically imported.
 *
 * <p>To compute median and the 90th and 99th percentiles:
 *
 * {@snippet :

    # Build a set of directory-based package roots (e.g. docs_src/bigger_applications/app_py39)
    # where at least one file is referenced in docs. All files in these directories
    # should be kept since they may be internally imported by the referenced files.
    used_package_dirs: set[Path] = set()
    for py_file in docs_src_path.rglob("*.py"):
        if py_file.name == "__init__.py":
            continue
        rel_path = str(py_file)

We also declare a special parameter of type `SecurityScopes`, imported from `fastapi.security`.

This `SecurityScopes` class is similar to `Request` (`Request` was used to get the request object directly).

We are importing the submodule `items` directly, instead of importing just its variable `router`.

This is because we also have another variable named `router` in the submodule `users`.

If we had imported one after the other, like:

```Python
from .routers.items import router
from .routers.users import router
```

depends on functionality of the <i>imported</i> package
(<a href="#Program_initialization_and_execution">§Program initialization and execution</a>)
and enables access to <a href="#Exported_identifiers">exported</a> identifiers
of that package.
The import names an identifier (PackageName) to be used for access and an ImportPath
that specifies the package to be imported.

Ainsi, la section :

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

va s'exécuter.

Cela ne se produira pas si vous importez ce module (fichier).

Par exemple, si vous avez un autre fichier `importer.py` qui contient :

```Python
from myapp import app

# Code supplémentaire
```

## Utiliser `WSGIMiddleware` { #using-wsgimiddleware }

/// info

Cela nécessite l'installation de `a2wsgi`, par exemple avec `pip install a2wsgi`.

///

Vous devez importer `WSGIMiddleware` depuis `a2wsgi`.

Ensuite, enveloppez l'application WSGI (par ex. Flask) avec le middleware.

Puis, montez-la sous un chemin.

Então, a seção:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)

Isso não acontecerá se você importar esse módulo (arquivo).

Então, se você tiver outro arquivo `importer.py` com:

```Python
from myapp import app

# Mais um pouco de código
```

nesse caso, a variável `__name__` criada automaticamente dentro de `myapp.py` não terá o valor `"__main__"`.

Então, a linha:
