Потім, використовуючи `random.choice()`, ми можемо отримати випадкове значення зі списку, тобто отримуємо кортеж із `(id, name)`. Це може бути щось на зразок `("imdb-tt0371724", "The Hitchhiker's Guide to the Galaxy")`.

Далі ми **присвоюємо ці два значення** кортежу змінним `id` і `name`.

Тож, якщо користувач не вказав ID елемента, він все одно отримає випадкову рекомендацію.

## Pythonで環境変数を読み取る

環境変数をPythonの**外側**、ターミナル（や他の方法）で作成し、**Python内で読み取る**こともできます。

例えば、以下のような`main.py`ファイルを用意します:

```Python hl_lines="3"
import os

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

/// tip

<a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> の第2引数は、デフォルトで返される値を指定します。

   * expression {@code o -> Optional.toJavaUtil(o)} instead.
   *
   * @since 33.4.0 (but since 21.0 in the JRE flavor)
   */
  @SuppressWarnings({
    "AmbiguousMethodReference", // We chose the name despite knowing this risk.
    "NullableOptional", // Null passthrough is reasonable for type conversions
  })
  // If users use this when they shouldn't, we hope that NewApi will catch subsequent Optional calls

Mittels einer Option direkt von Starlette können Sie einen *Pfad-Parameter* deklarieren, der einen Pfad enthalten soll, indem Sie eine URL wie folgt definieren:

```
/files/{file_path:path}
```

In diesem Fall ist der Name des Parameters `file_path`. Der letzte Teil, `:path`, sagt aus, dass der Parameter ein *Pfad* sein soll.

Sie verwenden das also wie folgt:

{* ../../docs_src/path_params/tutorial004_py39.py hl[6] *}

        this.fileIndex = fileIndex;
    }

    public void setFileName(final String fileName) {
        this.fileName = fileName;
    }

        String responseString = response.toString();
        assertTrue(responseString.startsWith("Trans2QueryFSInformationResponse["), "toString should start with the class name");
        // The toString implementation only includes the parent's toString, which may not include subCommand details
        assertNotNull(responseString);
        assertTrue(responseString.length() > 0);
    }

		os.Exit(1)
	}
	for _, input := range inputs {
		processFile(input, privateKeys)
	}
}

func processFile(inputFileName string, privateKeys [][]byte) {
	// Calculate the output file name
	var outputFileName string
	switch {
	case strings.HasSuffix(inputFileName, ".enc"):
		outputFileName = strings.TrimSuffix(inputFileName, ".enc") + ".zip"
	case strings.HasSuffix(inputFileName, ".zip"):

But you could customize it passing an additional argument with the directory name.

That command creates a new virtual environment in a directory called `.venv`.

You could create the virtual environment in a different directory, but there's a convention of calling it `.venv`.
