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.

De omgevingsvariabele `PATH` zou er bijvoorbeeld zo uit kunnen zien:

//// tab | Linux, macOS

            inf = new FileInternalInfo();
            break;
        default:
            return null;
        }
        return inf;
    }

    @Override
    public String toString() {
        return ("Trans2QueryPathInformationResponse[" + super.toString() + "]");
    }

* `allow_origins` - A list of origins that should be permitted to make cross-origin requests. E.g. `['https://example.org', 'https://www.example.org']`. You can use `['*']` to allow any origin.
* `allow_origin_regex` - A regex string to match against origins that should be permitted to make cross-origin requests. e.g. `'https://.*\.example\.org'`.

Así, en nuestro ejemplo, podemos hacer que `tags` sea específicamente una "lista de strings":

## Tipos de conjunto

Pero luego pensamos en ello, y nos damos cuenta de que los tags no deberían repetirse, probablemente serían strings únicos.

Y Python tiene un tipo de datos especial para conjuntos de elementos únicos, el `set`.

        // msg-type [1] INTEGER 14 (AP-REQ)
        v.add(new DERTaggedObject(true, 1, new ASN1Integer(Integer.parseInt(KerberosConstants.KERBEROS_AP_REQ))));
        // ap-options [2] BIT STRING
        v.add(new DERTaggedObject(true, 2, new DERBitString(new byte[] { apOptions }))); // first byte read by impl
        return new DERSequence(v);
    }

    @Test

    /** The number of items to display per page. */
    private int pageSize;

    /** The current page number. */
    private int currentPageNumber;

    /** The dictionary ID */
    public String id;

    /**
     * Clears all pagination data and resets to default values.
     */
    public void clear() {
        allRecordCount = 0;
        allPageCount = 0;
        existPrePage = false;
