### Dateien und Async { #files-and-async }

In den meisten Fällen sind dateiähnliche Objekte standardmäßig nicht mit async und await kompatibel.

Beispielsweise haben sie kein `await file.read()` oder `async for chunk in file`.

Und in vielen Fällen wäre das Lesen eine blockierende Operation (die die Event-Loop blockieren könnte), weil von der Festplatte oder aus dem Netzwerk gelesen wird.

/// info | Info

$ $Env:MY_NAME = "Wade Wilson"

// L'utiliser avec d'autres programmes, par exemple
$ echo "Hello $Env:MY_NAME"

Hello Wade Wilson
```

## Lire des variables d'environnement en Python { #read-env-vars-in-python }

Vous pouvez également créer des variables d'environnement **en dehors** de Python, dans le terminal (ou par tout autre moyen), puis les **lire en Python**.

Um **gerenciador de contexto** em Python é algo que você pode usar em uma declaração `with`, por exemplo, `open()` pode ser usado como um gerenciador de contexto:

```Python
with open("file.txt") as file:
    file.read()
```

Em versões mais recentes do Python, há também um **gerenciador de contexto assíncrono**. Você o usaria com `async with`:

```Python
async with lifespan(app):
    await do_stuff()
```

        }

        try {
            mimeMap = new MimeMap();
            is = getClass().getClassLoader().getResourceAsStream("jcifs/smb1/http/ne.css");
            while ((n = is.read(buf)) != -1) {
                sb.append(new String(buf, 0, n, "ISO8859_1"));
            }
            style = sb.toString();
        } catch (final IOException ioe) {
