from datetime import date

from pydantic import BaseModel

# 宣告一個變數為 string
# 並在函式中獲得 editor support
def main(user_id: str):
    return user_id


# 宣告一個 Pydantic model
class User(BaseModel):

可以像這樣來使用：

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

second_user_data = {
    "id": 4,
    "name": "Mary",

		expectedStatus int
		secretKey      string
		formData       map[string]string
	}{
		{http.StatusForbidden, credentials.SecretKey, map[string]string{"AWSAccessKeyId": "invalidaccesskey"}},
