## `PATH` Omgevingsvariabele

Er is een **speciale** omgevingsvariabele met de naam **`PATH`**, die door de besturingssystemen (Linux, macOS, Windows) wordt gebruikt om programma's te vinden die uitgevoerd kunnen worden.

De waarde van de variabele `PATH` is een lange string die bestaat uit mappen die gescheiden worden door een dubbele punt `:` op Linux en macOS en door een puntkomma `;` op Windows.

<a href="{{ sponsor.url }}" target="_blank" title="{{ sponsor.title }}"><img src="{{ sponsor.img }}" style="border-radius:15px"></a>
{% endfor -%}
{%- for sponsor in sponsors.silver -%}
<a href="{{ sponsor.url }}" target="_blank" title="{{ sponsor.title }}"><img src="{{ sponsor.img }}" style="border-radius:15px"></a>
{% endfor %}

* De variabele `items_s` is een `set`, en elk van de items is van het type `bytes`.

#### Dict

Om een `dict` te definiëren, geef je 2 typeparameters door, gescheiden door komma's.

De eerste typeparameter is voor de sleutels (keys) van de `dict`.

De tweede typeparameter is voor de waarden  (values) van het `dict`:

out the Fish-Footman was gone, and the other was sitting on the
ground near the door, staring stupidly up into the sky.

  Alice went timidly up to the door, and knocked.

  `There's no sort of use in knocking,' said the Footman, `and
that for two reasons.  First, because I'm on the same side of the
door as you are; secondly, because they're making such a noise
