/// tip | Tipp

Damit das funktioniert, müssen Sie `pip install python-dotenv` ausführen.

///

### Die `.env`-Datei

Sie könnten eine `.env`-Datei haben, mit:

```bash

labels.employeeNumber=Numer pracownika
labels.user_telephoneNumber=Numer telefonu
labels.telephoneNumber=Numer telefonu
labels.user_homePhone=Telefon (domowy)
labels.homePhone=Telefon (domowy)
labels.user_homePostalAddress=Adres pocztowy (domowy)
labels.homePostalAddress=Adres pocztowy (domowy)
labels.user_labeledURI=labeledURI
labels.labeledURI=labeledURI
labels.user_roomNumber=Numer pokoju
labels.roomNumber=Numer pokoju

/// tip

For this to work, you need to `pip install python-dotenv`.

///

### The `.env` file { #the-env-file }

You could have a `.env` file with:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

/// tip | Consejo

Para que esto funcione, necesitas `pip install python-dotenv`.

///

### El archivo `.env`

Podrías tener un archivo `.env` con:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

        assertEquals("DRguest", permissionHelper.encode("(deny){role}guest"));

        assertEquals("(deny){user}guest", permissionHelper.decode("D1guest"));
        assertEquals("(deny){group}guest", permissionHelper.decode("D2guest"));
        assertEquals("(deny){role}guest", permissionHelper.decode("DRguest"));

/// tip | Dica

Para que isso funcione você precisa executar `pip install python-dotenv`.

### O arquivo `.env`

Você pode definir um arquivo `.env` com o seguinte conteúdo:

```bash
ADMIN_EMAIL="******@****.***"

### Bewerk het

Dit is een heel eenvoudig programma.

Maar stel je nu voor dat je het vanaf nul zou moeten maken.

Op een gegeven moment zou je aan de definitie van de functie zijn begonnen, je had de parameters klaar...

Maar dan moet je “die methode die de eerste letter naar hoofdletters converteert” aanroepen.
