Hello everyone,
大家好，
I am pleased to announce the recent release of a new course on Udemy.
很高興宣布我最近在 Udemy 發布的一門新課程。
The course is on the extremely useful and versatile Pydantic (V2.x) library.
課程主題是極為實用且多功能的 Pydantic（V2.x）函式庫。
Although Pydantic is often perceived as something used for developing REST APIs (such as with FastAPI), it is in fact a generalized data modeling, parsing, and validation library with a ton of uses well beyond just REST APIs.
儘管 Pydantic 往往被視為用於開發 REST API（例如 FastAPI），實際上它是一個通用的資料建模、解析和驗證的函式庫，其用途遠遠超出了 REST API 的範圍。
In my opinion it is one of the most useful general-purpose libraries for Python software engineers.
在我看來，它是 Python 軟體工程師最有用的通用函式庫之一。
If you do any substantial amount of data validation, data modeling, parsing, and deserialization/serialization, then Pydantic is a must-have library in your toolkit!
如果你需要進行大量的資料驗證、資料建模、解析以及反序列化／序列化，那麼 Pydantic 就是你工具包中必備的函式庫！
I have used Pydantic on a daily basis for many years now, for applications ranging from handling queue messages (e.g. SQS, ElasticMQ, RabbitMQ), database JSON fields (e.g. Redis, DynamoDB, ClickHouse), to implementing validation for plain Python functions, and yes, FastAPI.
過去幾年我每天都在使用 Pydantic，應用範圍從處理佇列訊息（例如 SQS、ElasticMQ、RabbitMQ），數據庫 JSON 欄位（例如 Redis、DynamoDB、ClickHouse）到實作一般 Python 函式的驗證，當然還有 FastAPI。
It took me many years of working actively with this library to fully understand it, leverage it, and use it correctly and effectively. My aim with this course is to save you this time and effort, and provide you a simpler and faster route to achieving the same level of expertise.
我花了很多年的時間使用這個函式庫，才完全理解、利用，並正確有效地使用。我開設本課程的目的是為你節省時間和精力，並為你提供更簡單、更快捷的途徑，來達到相同的專業水平。
If you are interested in learning or deepening your understanding of Pydantic, here is a discounted coupon (as low as Udemy permits me!) for this course - but hurry, these coupons are only valid 5 days:
