并给出考核级别... 简单说, 协议早已设计好, 只是看是否都用足... HTTP 毕竟要向下兼容, 只是没想到大家没什么底线...


This step-by-step guide shows you the tools and tech you need to build a highly scalable data streaming pipeline in Python. It covers the use of Scrapy with Redis and a JSON based data flow.

This post shows you how to use the decision-trees algorithm with real-world data to predict cases of diabetes. Examples include the use of numpy, pandas, and sklearn.

This article gives an overview of type hints: what they are and when you should use them. It starts with simple types and builds up to more complex definitions.


反正就是好, 毕竟程序员不应该难为程序员, 自己麻烦点, 就可以帮助编译器进行各种优化, 虽然这种优化自己看不懂, 但是, 值得的...

最好再加上生命周期/所有权/...各种深层控制声明, pyrs 可能是个方向


Tips and tricks for inspecting Python objects and getting information about your code at runtime. Learn about built-in object methods and the inspect module.


反正没有什么是 print() 无法 print 的...


Karim writes about trying Rust programming as a 10+ years Python developer. He describes how to do common programming tasks and what the tooling looks like.

In this SQLAlchemy tutorial, you will learn to access and run SQL queries on all types of relational databases using Python objects.
