## 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:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

## Anwendungsfall { #use-case }

Beginnen wir mit einem Beispiel-**Anwendungsfall** und schauen uns dann an, wie wir ihn mit dieser Methode implementieren können.

Stellen wir uns vor, Sie verfügen über einige **Modelle für maschinelles Lernen**, die Sie zur Bearbeitung von Requests verwenden möchten. 🤖

    //                                                                        ============

    /**
     * Main method to start the Fess application.
     * Sets up system properties, configures Tomcat, and starts the server.
     *
     * @param args command line arguments (not used)

#### Blocking APIs

Blocking APIs are convenient because you get top-to-bottom procedural code without indirection. Network calls work like regular method calls: ask for data and it is returned. If the request fails, you get a stacktrace right where the call was made.
