While both American and British English are valid, establishing a single standard improves consistency, readability, and maintainability of the codebase.

## Decision

The Gradle project adopts **American English** as the standard language variant for all code, comments, documentation, user-facing messages, and written communication.

### Examples

## Dependencies { #dependencies }

FastAPI depends on Pydantic and Starlette.

### `standard` Dependencies { #standard-dependencies }

When you install FastAPI with `pip install "fastapi[standard]"` it comes with the `standard` group of optional dependencies:

Used by Pydantic:

In diesem Fall können Sie einfach die Standard-`dataclasses` durch `pydantic.dataclasses` ersetzen, was einen direkten Ersatz darstellt:

{* ../../docs_src/dataclasses_/tutorial003_py310.py hl[1,4,7:10,13:16,22:24,27] *}

1. Wir importieren `field` weiterhin von Standard-`dataclasses`.

2. `pydantic.dataclasses` ist ein direkter Ersatz für `dataclasses`.

In that case, you can simply swap the standard `dataclasses` with `pydantic.dataclasses`, which is a drop-in replacement:

{* ../../docs_src/dataclasses_/tutorial003_py310.py hl[1,4,7:10,13:16,22:24,27] *}

1. We still import `field` from standard `dataclasses`.

2. `pydantic.dataclasses` is a drop-in replacement for `dataclasses`.

### Without `fastapi-cloud-cli`

If you want to install FastAPI with the standard dependencies but without the `fastapi-cloud-cli`, you can install with `pip install "fastapi[standard-no-fastapi-cloud-cli]"`.

### Additional Optional Dependencies

There are some additional dependencies you might want to install.

### Sin Dependencias `standard` { #without-standard-dependencies }

Si no deseas incluir las dependencias opcionales `standard`, puedes instalar con `pip install fastapi` en lugar de `pip install "fastapi[standard]"`.

### Sin `fastapi-cloud-cli` { #without-fastapi-cloud-cli }

## Abhängigkeiten { #dependencies }

FastAPI hängt von Pydantic und Starlette ab.

### `standard`-Abhängigkeiten { #standard-dependencies }

Wenn Sie FastAPI mit `pip install "fastapi[standard]"` installieren, kommt es mit der `standard`-Gruppe optionaler Abhängigkeiten:

Verwendet von Pydantic:

### Без зависимостей `standard` { #without-standard-dependencies }

Если вы не хотите включать опциональные зависимости `standard`, можно установить `pip install fastapi` вместо `pip install "fastapi[standard]"`.

### Без `fastapi-cloud-cli` { #without-fastapi-cloud-cli }

Если вы хотите установить FastAPI со стандартными зависимостями, но без `fastapi-cloud-cli`, установите `pip install "fastapi[standard-no-fastapi-cloud-cli]"`.

## Dependências { #dependencies }

### Dependências `standard` { #standard-dependencies }

Quando você instala o FastAPI com `pip install "fastapi[standard]"`, ele vêm com o grupo `standard` (padrão) de dependências opcionais:
