### Umgebungsvariablen mit Python auslesen

Sie können Umgebungsvariablen auch außerhalb von Python im Terminal (oder mit einer anderen Methode) erstellen und diese dann mit Python auslesen.

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

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")

If you are building a <abbr title="Command Line Interface">CLI</abbr> app to be used in the terminal instead of a web API, check out <a href="https://typer.tiangolo.com/" class="external-link" target="_blank">**Typer**</a>.

**Typer** is FastAPI's little sibling. And it's intended to be the **FastAPI of CLIs**. ⌨️ 🚀

**Typer** es el hermano menor de FastAPI.  La intención es que sea el **FastAPI de las CLIs**. ⌨️ 🚀

Typer CLIをインストールする場合、次のコマンドで補完をインストールできます:

<div class="termy">

```console
$ typer --install-completion

zsh completion installed in /home/user/.bashrc.
Completion will take effect once you restart the terminal.
```

</div>

### アプリとドキュメントを同時に

以下の様にサンプルを実行すると:

<div class="termy">

```console
$ uvicorn tutorial001:app --reload

import org.opensearch.search.sort.SortOrder;

public interface FessProp {

    String API_PING_SEARCH_ENGINE_FIELD_SET = "apiPingSearchEngineFieldSet";

    String QUERY_HIGHLIGHT_TERMINAL_CHARS = "queryHighlightTerminalChars";

    String QUERY_HIGHLIGHT_BOUNDARY_CHARS = "queryHighlightBoundaryChars";

    String QUERY_TRACK_TOTAL_HITS_VALUE = "queryTrackTotalHitsValue";

This will probably happen for more than one of those tabs.

If you had multiple clients talking to your app exactly at the same time, this is what could happen.
