### 建立 `Settings` 物件 { #create-the-settings-object }

從 Pydantic 匯入 `BaseSettings` 並建立子類別，與建立 Pydantic model 的方式非常類似。

就像使用 Pydantic model 一樣，你用型別註解宣告類別屬性，並可選擇性地提供預設值。

你可以使用與 Pydantic model 相同的所有驗證功能與工具，例如不同的資料型別與透過 `Field()` 進行額外驗證。

/// tip

如果你想要可以直接複製貼上的範例，先別用這個，請改用本文最後一個範例。

///

from datetime import date

from pydantic import BaseModel

# Déclarez une variable comme étant une str
# et profitez de l'aide de l'éditeur dans cette fonction
def main(user_id: str):
    return user_id


# Un modèle Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Qui peuvent ensuite être utilisés comme ceci :

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

}

func BenchmarkMutexWorkSlack(b *testing.B) {
	benchmarkMutex(b, true, true)
}

func BenchmarkMutexNoSpin(b *testing.B) {
	b.ResetTimer()
	b.ReportAllocs()

	// This benchmark models a situation where spinning in the mutex should be
	// non-profitable and allows to confirm that spinning does not do harm.
	// To achieve this we create excess of goroutines most of which do local work.
