If you need a 2 minute refresher of how to use Python types (even if you don't use FastAPI), check the short tutorial: [Python Types](python-types.md).

You write standard Python with types:

```Python
from datetime import date

from pydantic import BaseModel

# Declare a variable as a str
# and get editor support inside the function
def main(user_id: str):
    return user_id


# A Pydantic model

             value JSON)
           CHARACTER SET = utf8mb4 COLLATE = utf8mb4_bin ROW_FORMAT = Dynamic;`
	mysqlCreateAccessTable = `CREATE TABLE %s (event_time DATETIME NOT NULL, event_data JSON)
                                    ROW_FORMAT = Dynamic;`

	mysqlUpdateRow = `INSERT INTO %s (key_name, value) VALUES (?, ?) ON DUPLICATE KEY UPDATE value=VALUES(value);`

    // Date/Time Format Constants
    // ============================================================

    /** Default datetime format pattern without timezone. */
    public static final String DEFAULT_DATETIME_FORMAT = "yyyy-MM-dd'T'HH:mm:ss";

    /** ISO datetime format pattern with milliseconds and UTC timezone. */
    public static final String ISO_DATETIME_FORMAT = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'";

（FastAPI を使わない場合でも）Python の型の使い方を 2 分で復習したい場合は、短いチュートリアル [Python の型](python-types.md) を参照してください。

型を使った標準的な Python を記述します:

```Python
from datetime import date

from pydantic import BaseModel

# Declare a variable as a str
# and get editor support inside the function
def main(user_id: str):
    return user_id


# A Pydantic model

全部都基于标准的 **Python 类型** 声明（感谢 Pydantic）。没有新的语法需要学习。只需要标准的现代 Python。

如果你需要2分钟来学习如何使用 Python 类型（即使你不使用 FastAPI），看看这个简短的教程：[Python 类型](python-types.md)。

编写带有类型标注的标准 Python：

```Python
from datetime import date

from pydantic import BaseModel

# 将变量声明为 str
# 并在函数内获得编辑器支持
def main(user_id: str):
    return user_id


# 一个 Pydantic 模型
class User(BaseModel):
    id: int
    name: str

這一切都基於標準的 **Python 型別**宣告（感謝 Pydantic）。無需學習新的語法，只需使用標準的現代 Python。

如果你需要 2 分鐘來學習如何使用 Python 型別（即使你不使用 FastAPI），可以看看這個簡短的教學：[Python 型別](python-types.md)。

如果你寫帶有 Python 型別的程式碼：

```Python
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):
    id: int
