• 简单的选择就是 Pytest
  • PyTest

During my work as Python developer, I have seen many different approaches to software testing. Having such developed community and tools, it may seem that this topic should not leave much to discuss in the Python world. For many developers the choice of their test framework might be simple?—?Pytest.

• Python 中垃圾收集需要了解的事情
  • garbage collection

This article describes garbage collection (GC) in Python 3.6. Usually, you don't need to worry about memory management when the objects are no longer needed Python automatically reclaims the memory from them. However, understanding how GC works can help you write better Python programs.

• Tensorflow 文本分类
  • text classification

Text Classification is the task of assigning the right label to a given piece of text. This text can either be a phrase, a sentence or even a paragraph. Our aim would be to take in some text as input and attach or assign a label to it. Since we will be using Tensorflow deep learning library, we can call this the Tensorflow text classification system.

• 稳定排序
  • code snippets

Stable sorting maintains the original order if two keys are the same

• 使用 UUID 作为主键
  • UUID

If you’re designing a REST API, auto incremented primary keys can be a threat. They expose a lot of informations about your API and the internal structure. UUIDs can help to cover these information and make your API more secure. In the following I’m going to explain what a primary key is and what problems can occur with auto incremented primary keys.

• GetStream.io: 为什么我们从Python切换到Go
  • golang

Switching to a new language is always a big step, especially when only one of your team members has prior experience with that language. Early this year, we switched Stream’s primary programming language from Python to Go. This post will explain some of the reasons why we decided to leave Python behind and make the switch to Go.

• 危险的 Pickles - Python 序列化
  • pickles

Before we get elbow deep in opcodes here, let’s cover a little background. The Python standard library has a module called pickle that is used for serializing and deserializing objects. Except it’s not called serializing and deserializing, it’s pickling and unpickling.

• 用Python 的 Scikit 来介绍机器学习
  • scikit

In this post, we'll be doing a step-by-step walkthrough of a basic machine learning project, geared toward people with some knowledge of programming (preferably Python), but who don’t have much experience with machine learning. By the end of this post, you'll understand what machine learning is, how it can help you, and be able to build your own machine learning classifiers for any dataset you want.

• Python 循环导入
  • core-python

A circular dependency occurs when two or more modules depend on each other. This is due to the fact that each module is defined in terms of the other.
