Python 的类型类 NIKITA SOBOLEV • Shared by Nikita Sobolev Sometimes you need to change the behavior of a function based on the type of argument passed to it. This is a classic example of polymorphism in programming. In this article, you’ll learn how this is typically done in Python, compare that to polymorphism in other languages, and see how the new classes library can make the whole process easier. Django REST 框架中/自定义权限类 TESTDRIVEN.IO • Shared by Špela Giacomelli (aka GirlLovesToCode) One of the great things about Django REST Framework (DRF) is how easy it is to be productive with the built-in API views and permission classes. But sometimes you need a bit more control than the built-in objects allow. This article walks you through how to create and use custom permission classes in DRF so that you can have complete control over how permissions work in your REST API.

Python Redux 中的子类化 HYNEK SCHLAWACK Have you ever heard someone say that composition is better than inheritance? It’s an age-old conflict in object-oriented programming that’s been the impetus for numerous online debates. Author Hynek Schlawack, who describes himself as “firmly in the composition-over-inheritance camp” explains in this article how “Python is designed in a way that you can’t write idiomatic code without subclassing sometimes.” (是也乎: 组合总比继承香? 看场景了, 如果要分包给印度弟兄们, 还是继承吧… ) Python 中的相关分析初步 OLGA BEREZOVSKY • Shared by Olga Berezovsky Correlation analysis is a useful part of exploratory data analysis.
