Changes to the pip Dependency Resolver in 20.2
Changes in the behavior ofpip installwill reduce inconsistency and make it stricter. Pip will no longer install a combination of packages that is mutually inconsistent and if you ask pip to install two packages with incompatible requirements, it will refuse (rather than installing a broken combination, like it did in previous versions).These changes will become the default in pip 20.3, due to be released in October.

总体来讲还是比CPython快很多的
缺点是
- 跟C拓展不兼容，用起来会很慢，如果可以建议把C拓展换成纯Python实现的
- PyPy基本只适用于长时间运行的程序，如果只是一个简单的脚本，大可不必
- PyPy的解释器还是动态的，不能像C一样直接编译成可执行文件

Why Should You Use an ORM (Object Relational Mapper)?
Budding web developers learning Model-View-Controller frameworks are taught that they should use an Object Relational Mapper (ORM) to interface with their databases. But the “why” is often brushed aside or omitted entirely, leaving a fledgling programmer with burning questions like ”What are ORMs, anyway?” and “What problems do they solve?”
