`Header` ist eine „Schwester“-Klasse von `Path`, `Query` und `Cookie`. Sie erbt ebenfalls von der gemeinsamen `Param`-Klasse.

Aber denken Sie daran, dass bei der Nutzung von `Query`, `Path`, `Header` und anderen Importen aus `fastapi`, diese tatsächlich Funktionen sind, die spezielle Klassen zurückgeben.

따라서 섹션

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

이 실행됩니다.

해당 모듈(파일)을 가져오면 이런 일이 발생하지 않습니다

그래서 다음과 같은 다른 파일 `importer.py`가 있는 경우:

```Python
from myapp import app

# Some more code
```

이 경우 `myapp.py` 내부의 자동 변수 `__name__`에는 값이 `"__main__"`이 들어가지 않습니다.

따라서 다음 행

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

Pydantic v2 inclut tout Pydantic v1 sous la forme du sous-module `pydantic.v1`. Mais cela n'est plus pris en charge dans les versions au-delà de Python 3.13.

Cela signifie que vous pouvez installer la dernière version de Pydantic v2 et importer/utiliser les anciens composants de Pydantic v1 depuis ce sous-module, comme si vous aviez l'ancien Pydantic v1 installé.

Certifique-se de criar um [ambiente virtual](../virtual-environments.md), ativá-lo e então instalar, por exemplo:

```console
$ pip install python-multipart

# "TFCI" may optionally be set to the name of an env-type file with TFCI
# variables in it, OR may be left empty if the user has already exported the
# relevant variables in their environment. Because of 'set -o allexport' above
# (which is equivalent to "set -a"), every variable in the file is exported
# for other files to use.
#
# Separately, if TFCI is set *and* there are also additional TFCI_ variables
