When Should You Upgrade to Python 3.12?
Python 3.12 has been released—when should you switch to using it? ITAMAR TURNER-TRAURING

文章中说的很合理，如果你的Python版本落后太多，那么升级到最新的3.12就太可怕了，这种情况下，应该从3.8、3.9、3.10到3.11、3.12逐步升级上来。升级其实主要顾虑的就是第三方库的兼容性，还有就是项目中一些编译好的.so需要重新编译

Inline Dependencies for Small Python Scripts
Sabs wanted the ability to specify dependencies inside a single Python script, and although there are PEPs on this topic, their implementation is a ways off. Sabs decided to solve this problem directly: introducing pip.wtf a code snippet you copy into your script that does dependency loading through a function call. PIP.WTF

Why if TYPE_CHECKING?
“Typechecking is brittle yet important”, learn more about where it works and where it doesn’t and what that might mean for your code. VICKI BOYKIS

读一下这篇文章，讲了Python的类型提示的历史，以及为什么要用类型提示，以及类型提示的局限性里面提到了Python的基本数据类型包括

int, float, complex
str
bytes
tuple
frozenset
bool
array
bytearray
list
set

Real-World match/case
The match statement was added in Python 3.10. This article covers a real-world example use case and shows its power. NED BATCHELDER

match case的酷炫用法

# Check the structure of the payload:
match event:
    case {
        "issue": {"closed_at": closed},
        "comment": {"created_at": commented},
        } if closed == commented:
        # This is a "Close with comment" comment. Don't do anything for the
        # comment, because we'll also get a "pull request closed" event at
        # the same time, and it will do whatever we need.
        pass

    case {"sender": {"login": who}} if who == get_bot_username():
        # When the bot comments on a pull request, it causes an event, which
        # gets sent to webhooks, including us.  We don't have to do anything
        # for our own comment events.
        pass

    case {"issue": {"pull_request": _}}:
        # The comment is on a pull request. Process it.
