`PUT`は、既存のデータを置き換えるべきデータを受け取るために使用されます。

### 置換についての注意 { #warning-about-replacing }

つまり、`PUT`を使用して以下のボディで項目`bar`を更新したい場合は:

```Python
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

すでに格納されている属性`"tax": 20.2`を含まないため、入力モデルは`"tax": 10.5`のデフォルト値を取ります。

そして、データはその「新しい」`10.5`の`tax`と共に保存されます。

## `PATCH`による部分的な更新 { #partial-updates-with-patch }

Você também pode criar uma variável de ambiente apenas para uma **invocação específica do programa**, que só está disponível para aquele programa e apenas pela duração dele.

Para fazer isso, crie-a na mesma linha, antes do próprio programa:

<div class="termy">

```console
// Criar uma variável de ambiente MY_NAME para esta chamada de programa
$ MY_NAME="Wade Wilson" python main.py

Вы будете получать автозавершение кода даже там, где вы считали это невозможным раньше. Как пример, ключ `price` внутри тела JSON (который может быть вложенным), приходящего в запросе.

Sie bekommen sogar Autovervollständigung an Stellen, an denen Sie dies vorher nicht für möglich gehalten hätten. Zum Beispiel der `price` Schlüssel in einem JSON Datensatz (dieser könnte auch verschachtelt sein), der aus einem Request kommt.
