Wenn Sie bereit sind, ein **Tool zu verwenden, das alles für Sie verwaltet** (einschließlich der Installation von Python), probieren Sie [uv](https://github.com/astral-sh/uv).

## Ein Projekt erstellen { #create-a-project }

Erstellen Sie zuerst ein Verzeichnis für Ihr Projekt.

Was ich normalerweise mache, ist, dass ich ein Verzeichnis namens `code` in meinem Home/Benutzerverzeichnis erstelle.

Si vous êtes prêt à adopter un outil qui gère tout pour vous (y compris l’installation de Python), essayez [uv](https://github.com/astral-sh/uv).

## Créer un projet { #create-a-project }

Commencez par créer un répertoire pour votre projet.

Ce que je fais généralement, c’est créer un répertoire nommé `code` dans mon répertoire personnel/utilisateur.

        final Tuple3<String, String, String> task = new Tuple3<>(getName(), thumbnailId, path);
        if (logger.isDebugEnabled()) {
            logger.debug("Create thumbnail task: {}", task);
        }
        return task;
    }

    /**
     * Sets the directory name length for thumbnail storage.
     * @param directoryNameLength The directory name length.
     */

    @BeforeEach
    void setUp() {
        mockConfig = mock(Configuration.class);
        response = new Smb2TreeDisconnectResponse(mockConfig);
    }

    @Test
    @DisplayName("Should create response with configuration")
    void testConstructorWithConfiguration() {
        // Given & When
        Smb2TreeDisconnectResponse resp = new Smb2TreeDisconnectResponse(mockConfig);

        // Then

        mocks = MockitoAnnotations.openMocks(this);

        when(context.getConfig()).thenReturn(config);
        when(config.isDirectoryNotificationsEnabled()).thenReturn(false);

        // Create real lease manager for integration testing
        baseLeaseManager = new LeaseManager(context);
        directoryLeaseManager = new DirectoryLeaseManager(context, baseLeaseManager);
    }

    @AfterEach

Umgebungsvariablen können nützlich sein, um **Einstellungen** der Anwendung zu handhaben, als Teil der **Installation** von Python usw.

## Umgebungsvariablen erstellen und verwenden { #create-and-use-env-vars }

Sie können Umgebungsvariablen in der **Shell (Terminal)** erstellen und verwenden, ohne Python zu benötigen:
