• 将 Python 语法编译为 x86-64 指令集只为好玩并无增益
  • AST

I used Python’s built-in AST module to parse a subset of Python syntax and turn it into an x86-64 assembly program. It’s basically a toy, but it shows how easy it is to use the ast module to co-opt Python’s lovely syntax for your own ends.

简单的说, 就是内置 AST 能力的嗯哼... )

• 如何在 Python 中设立基准性能
  • performance

Suppose that you have a function and you wonder, "Can I make this faster?" Well, you might already have thought that and you might already have a theory. Or two. Or three. Your theory might be sound and likely to be right, but before you go anywhere with it you need to benchmark it first. Here are some tips and scaffolding for doing Python function benchmark comparisons.

• Kruskal 的算法可视化
  • algorithms

Kruskal’s algorithm is a greedy algorithm that finds a minimum spanning tree for a weighted undirected garph. Visualisation and code snippet included.

• 在 Python 基于贝叶斯进行 AB 测试
  • A/B-Testing

Back when I was getting started into Bayesian Statistics I found it hard to find some simple ready-to-use code examples to get started with probabilistic programming. Today, there are great resources available and I want to contribute with that sharing a very simple code to get started with AB Tests in Python.

• 使用 nose 以及 coverage 进行 Django 测试
  • django, testing

Django testing using django-nose and coverage.

• 用 scikit-learn, AWS Lambda, S3 和 Amazon API Gateway 构建接口
  • scikit, s3, lamda

This tutorial will help you build a classifier as a service. The classifier will be trained using iris flower data set witch consists on 3 different types of irises’ (Setosa, Versicolour, and Virginica). The rows being the samples and the columns being features: sepal length, sepal width, petal length and petal width. Scikit-learn library will be used for machine-learning algorithms.

• logzero - 简化 Python 2 和 3 的 logging
  • logging

I’ve just published logzero, a small Python package which simplifies logging with Python 2 and 3. It is easy to use and robust, and heavily inspired by the Tornado web framework.

• CPython 和 MicroPython 中的内存应用
  • micropython

At PyCon 2017, Kavya Joshi looked at some of the differences between the Python reference implementation (known as "CPython") and that of MicroPython. In particular, she described the differences in memory use and handling between the two. Those differences are part of what allows MicroPython to run on the severely memory-constrained microcontrollers it targets—an environment that could never support CPython.

• Solid
  • 0 Stars, 0 Fork

A comprehensive gradient-free optimization framework written in Python. It contains basic versions of many of the most common optimization algorithms that do not require the calculation of gradients, and allows for very rapid development using them. It's a very versatile library that's great for learning, modifying, and of course, using out-of-the-box.
