# Get Current User

In the previous chapter the security system (which is based on the dependency injection system) was giving the *path operation function* a `token` as a `str`:

//// tab | Python 3.9+

```Python hl_lines="12"
{!> ../../docs_src/security/tutorial001_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="11"
{!> ../../docs_src/security/tutorial001_an.py!}
```

////

## List of models

The same way, you can declare responses of lists of objects.

For that, use the standard Python `typing.List` (or just `list` in Python 3.9 and above):

//// tab | Python 3.9+

```Python hl_lines="18"
{!> ../../docs_src/extra_models/tutorial004_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="1  20"

//// tab | Python 3.9+

Python 3.9-এ, `Annotated` স্ট্যান্ডার্ড লাইব্রেরিতে অন্তর্ভুক্ত, তাই আপনি এটি `typing` থেকে ইমপোর্ট করতে পারেন।

```Python hl_lines="1  4"
{!> ../../docs_src/python_types/tutorial013_py39.py!}
```

////

//// tab | Python 3.8+

Python 3.9-এর নীচের সংস্করণগুলিতে, আপনি `Annotated`-কে `typing_extensions` থেকে ইমপোর্ট করেন।

//// tab | Python 3.9+

In Python 3.9 is `Annotated` onderdeel van de standaardpakket, dus je kunt het importeren vanuit `typing`.

```Python hl_lines="1  4"
{!> ../../docs_src/python_types/tutorial013_py39.py!}
```

////

//// tab | Python 3.8+

In versies lager dan Python 3.9 importeer je `Annotated` vanuit `typing_extensions`.

Z. B. `pip install python-multipart`.

///

## `File` und `Form` importieren

//// tab | Python 3.9+

```Python hl_lines="3"
{!> ../../docs_src/request_forms_and_files/tutorial001_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="1"

You could create a first dependency ("dependable") like:

//// tab | Python 3.10+

```Python hl_lines="8-9"
{!> ../../docs_src/dependencies/tutorial005_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="8-9"
{!> ../../docs_src/dependencies/tutorial005_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="9-10"
{!> ../../docs_src/dependencies/tutorial005_an.py!}

//// tab | Python 3.10+

```Python hl_lines="28-33"
{!> ../../docs_src/body_updates/tutorial001_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="30-35"
{!> ../../docs_src/body_updates/tutorial001_py39.py!}
```

////

//// tab | Python 3.6+

```Python hl_lines="30-35"
{!> ../../docs_src/body_updates/tutorial001.py!}
```

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

///

## Import `File` and `Form`

//// tab | Python 3.9+

```Python hl_lines="3"
{!> ../../docs_src/request_forms_and_files/tutorial001_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="1"

У цьому випадку, `str` це параметр типу переданий у `List` (або `list` у Python 3.9 і вище).

///

Це означає: "змінна `items` це `list`, і кожен з елементів у цьому списку - `str`".

/// tip

Якщо ви використовуєте Python 3.9 і вище, вам не потрібно імпортувати `List` з `typing`, ви можете використовувати натомість тип `list`.
