* `datetime.datetime`:
    * Встроенный в Python `datetime.datetime`.
    * В запросах и ответах будет представлен как `str` в формате ISO 8601, например: `2008-09-15T15:53:00+05:00`.
* `datetime.date`:
    * Встроенный в Python `datetime.date`.
    * В запросах и ответах будет представлен как `str` в формате ISO 8601, например: `2008-09-15`.
* `datetime.time`:
    * Встроенный в Python `datetime.time`.

* If you are in a Python version lower than 3.9, import their equivalent version from the `typing` module
* Pass the internal type(s) as "type parameters" using square brackets: `[` and `]`

In Python 3.9 it would be:

```Python
my_list: list[str]
```

In versions of Python before 3.9, it would be:

```Python
from typing import List

my_list: List[str]
```

### What are "Context Managers" { #what-are-context-managers }

"Context Managers" are any of those Python objects that you can use in a `with` statement.

For example, <a href="https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files" class="external-link" target="_blank">you can use `with` to read a file</a>:

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

Ezt standard modern Python típusokkal csinálod.

Nem kell új szintaxist, vagy specifikus könyvtár mert metódósait, stb. megtanulnod.

Csak standard **Python**.

Például egy `int`-nek:

```Python
item_id: int
```

Egy komplexebb `Item` modellnek:

```Python
item: Item
```

... És csupán egy deklarációval megkapod a:

//tensorflow/python:mixed_precision
//tensorflow/python:tf_optimizer
//tensorflow/python:compare_test_proto_py
//tensorflow/python/framework:test_file_system.so
//tensorflow/python/debug:grpc_tensorflow_server.par
//tensorflow/python/feature_column:vocabulary_testdata
//tensorflow/python/util:nest_test_main_lib
//tensorflow/lite/experimental/examples/lstm:rnn_cell
//tensorflow/lite/experimental/examples/lstm:rnn_cell.py

# Paramètres de chemin

Vous pouvez déclarer des "paramètres" ou "variables" de chemin avec la même syntaxe que celle utilisée par le
<a href="https://docs.python.org/fr/3/library/string.html#format-string-syntax" class="external-link" target="_blank">formatage de chaîne Python</a> :


{* ../../docs_src/path_params/tutorial001.py hl[6:7] *}

La valeur du paramètre `item_id` sera transmise à la fonction dans l'argument `item_id`.

### Gewoon Moderne Python

Het is allemaal gebaseerd op standaard **Python type** declaraties (dankzij Pydantic). Je hoeft dus geen nieuwe syntax te leren. Het is gewoon standaard moderne Python.

Als je een opfriscursus van 2 minuten nodig hebt over het gebruik van Python types (zelfs als je FastAPI niet gebruikt), bekijk dan deze korte tutorial: [Python Types](python-types.md){.internal-link target=_blank}.

* `datetime.datetime`:
    * O `datetime.datetime` do Python.
    * Em requisições e respostas será representado como uma `str` no formato ISO 8601, exemplo: `2008-09-15T15:53:00+05:00`.
* `datetime.date`:
    * O `datetime.date` do Python.
    * Em requisições e respostas será representado como uma `str` no formato ISO 8601, exemplo: `2008-09-15`.
* `datetime.time`:
    * O `datetime.time` do Python.

You can import it directly form `fastapi`:

```python
from fastapi import WebSocketDisconnect
```

::: fastapi.WebSocketDisconnect

## WebSockets - additional classes

Additional classes for handling WebSockets.

Provided directly by Starlette, but you can import it from `fastapi`:

```python
from fastapi.websockets import WebSocketDisconnect, WebSocketState
```
