Creating Beautiful Tracebacks with Python’s Exception Hooks
“We all spend a good chunk of our time debugging, sifting through logs, or reading tracebacks. Each of these can be difficult and time-consuming and in this article, we will focus on making the last one—dealing with tracebacks and exceptions—as easy and efficient as possible.” MARTIN HEINZ • Shared by Martin Heinz

还是PySimpleGUI好用，pyhon干gui实在是太挫了
Issue #512 Unit Test Docs, Python zipfile, Django Runs Black, and More Feb. 15, 2022¶
Documentation Unit Tests
Interesting approach to keeping documentation and code in sync: introspecting the code to figure out what needs to be documented, then parsing the documentation to see if each item has been covered. SIMON WILLISON
没仔细看
PEP 673: Self Type Was Accepted
This PEP introduces a simple and intuitive way to annotate methods that return an instance of their class. This behaves the same as the TypeVar-based approach specified in PEP 484 but is more concise and easier to follow. Related Twitter thread by core dev Raymond Hettinger. PYTHON.ORG

Upcoming Python Feature PEPs
“These PEPs are a great way of getting the freshest info about what might be included in the upcoming Python releases. So, in this article we will go over all the proposals that are going to bring some exciting new Python features in a near future!” MARTIN HEINZ
这个pep https://python.org/dev/peps/pep-0654/ 咋看着这么狂野。 看了一下pep还是很合理的，很多时候需要一次raise多个不同的exception，目前是没办法做的。 不过这玩意等实现估计得要3.11往后了吧

How to Create a Generator Function
Generators are iterators that don’t take up the memory. Have a function that returns a list? You may be able to turn it into a generator function by replacing the append() calls with yield statements. TREY HUNNER
使用yield关键字来吧普通的函数转换为生成器函数

Processing Large JSON Files Without Running Out of Memory
Loading complete JSON files into Python can use too much memory, leading to slowness or crashes. The solution: process JSON data one chunk at a time. ITAMAR TURNER-TRAURING

In this tutorial, you’ll learn all about working with YAML in Python. By the end of it, you’ll know about the available libraries, their strengths and weaknesses, and the advanced and potentially dangerous features of YAML. You’ll also serialize Python objects and create a YAML syntax highlighter. REAL PYTHON
json的一个问题就是一个大的对象需要一次性load进来，不能像txt一样一行一行写
