## Umgebungsvariablen in Python lesen { #read-env-vars-in-python }

Sie können auch Umgebungsvariablen **außerhalb** von Python erstellen, im Terminal (oder mit jeder anderen Methode) und sie dann **in Python** lesen.

Zum Beispiel könnten Sie eine Datei `main.py` haben mit:

Ein **Kontextmanager** in Python ist etwas, das Sie in einer `with`-Anweisung verwenden können, zum Beispiel kann `open()` als Kontextmanager verwendet werden:

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

In neueren Versionen von Python gibt es auch einen **asynchronen Kontextmanager**. Sie würden ihn mit `async with` verwenden:

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

		for j := 0; j < loopCount; j++ {
			var tmp User
			err := tx.Session(&gorm.Session{}).First(&tmp, id).Error
			if err == nil || isUsingClosedConnError(err) {
				continue
			}
			t.Errorf("failed to read user of id %d due to %s, there should not be error", id, err)
			unexpectedError = true
			break
		}
	}(user.ID)

	wg.Add(1)
	go func() {
		defer wg.Done()
		<-writerFinish
		pdb.Close()
	}()

        int maxCount = buf.dec_ndr_long();
        int offset = buf.dec_ndr_long();
        int actualCount = buf.dec_ndr_long();

        if (actualCount <= 0) {
            return "";
        }

        // Read wide string data (UTF-16LE)
        int byteCount = (actualCount - 1) * 2; // Exclude null terminator
        byte[] wideBytes = new byte[byteCount];
        buf.readOctetArray(wideBytes, 0, byteCount);

This will generate a TypeScript SDK in `./src/client`.

You can learn how to [install `@hey-api/openapi-ts`](https://heyapi.dev/openapi-ts/get-started) and read about the [generated output](https://heyapi.dev/openapi-ts/output) on their website.

### Using the SDK { #using-the-sdk }

### Файл `.env` { #the-env-file }

У вас может быть файл `.env` со следующим содержимым:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

### Чтение настроек из `.env` { #read-settings-from-env }

Затем обновите ваш `config.py` так:

{* ../../docs_src/settings/app03_an_py310/config.py hl[9] *}

Örneğin, [bir dosyayı okumak için `with` kullanabilirsiniz](https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files):

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

Temelde `open("./somefile.txt")`, "Context Manager" olarak adlandırılan bir nesne oluşturur.

`with` bloğu bittiğinde, exception olsa bile dosyanın kapatılmasını garanti eder.

variables as part of those interactions (ex: using a string variable to build a
filesystem path), a maliciously created checkpoint might be able to change the
targets of those operations, which could result in arbitrary
read/write/executions.

TensorFlow is a platform for distributed computing, and as such there is a
TensorFlow server (`tf.train.Server`). The TensorFlow server is intended for
