Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console
$ pip install python-multipart
```

///

## Import `Form`

Import `Form` from `fastapi`:

//// tab | Python 3.9+

```Python hl_lines="3"

                    .build());
            options.addOption(Option.builder(ACTIVATE_PROFILES)
                    .longOpt("activate-profiles")
                    .desc(
                            "Comma-delimited list of profiles to activate. Prefixing a profile with ! excludes it, and ? marks it as optional")
                    .hasArg()
                    .build());

Например, у вас есть 4 API-эндпоинта (*операции пути*):

- `/items/public/`
- `/items/private/`
- `/users/{user_id}/activate`
- `/items/pro/`

Тогда вы можете требовать разные права для каждого из них, используя зависимости и подзависимости:

```mermaid
graph TB

current_user(["current_user"])
active_user(["active_user"])

Nehmen wir zum Beispiel an, Sie haben vier API-Endpunkte (*Pfadoperationen*):

* `/items/public/`
* `/items/private/`
* `/users/{user_id}/activate`
* `/items/pro/`

Dann könnten Sie für jeden davon unterschiedliche Berechtigungsanforderungen hinzufügen, nur mit Abhängigkeiten und Unterabhängigkeiten:

```mermaid
graph TB

    runs-on: ubuntu-latest
    steps:
      - uses: actions/stale@v9
        with:
          operations-per-run: 50
          ascending: true
          exempt-all-milestones: true

          # ISSUES (deactivated) ----------------------------------------------
          # This workflow should touch no issues, so times are set to -1
          # (see actions/stale documentation for the behavior)
          days-before-issue-stale: -1
