* La variable `items_s` est un `set`, et chacun de ses éléments est de type `bytes`.

#### `Dict`

Pour définir un `dict`, il faut lui passer 2 paramètres, séparés par une virgule (`,`).

Le premier paramètre de type est pour les clés et le second pour les valeurs du dictionnaire (`dict`).

{*../../docs_src/python_types/tutorial008.py hl[1,4] *}

Dans cet exemple :

<div class="termy">

```console
$ C:\opt\custompython\bin\python
```

</div>

## Conclusion

Hiermee heb je basiskennis van wat **omgevingsvariabelen** zijn en hoe je ze in Python kunt gebruiken.

O valor da variável `PATH` é uma longa string composta por diretórios separados por dois pontos `:` no Linux e macOS, e por ponto e vírgula `;` no Windows.

Por exemplo, a variável de ambiente `PATH` poderia ter esta aparência:

//// tab | Linux, macOS

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
```

          @Override
          public void tearDown() throws Exception {
            synchronized (result.lock) {
              assertEquals(
                  "The test should have cleared the stack (say, by virtue of running runTearDown)",
                  0,
                  result.stack.size());
            }
          }
        });
    return result;
  }

* `items_t` değişkeni sırasıyla `int`, `int`, ve `str` tiplerinden oluşan bir `tuple` türündedir .
* `items_s` ise her öğesi `bytes` türünde olan bir `set` örneğidir.

#### `Dict`

Bir `dict` tanımlamak için virgülle ayrılmış iki parametre verebilirsiniz.

İlk tip parametresi `dict` değerinin `key` değeri içindir.

İkinci parametre ise `dict` değerinin `value` değeri içindir:

      /*
       * FinalizableReference's class loader was reclaimed. While there's a chance that other
       * finalizable references could be enqueued subsequently (at which point the class loader
       * would be resurrected by virtue of us having a strong reference to it), we should pretty
       * much just shut down and make sure we don't keep it alive any longer than necessary.
