• Python 哈希和对等
  • core-python

Most Python programmers don’t spend a lot of time thinking about how equality and hashing works. It usually just works. However there’s quite a bit of gotchas and edge cases that can lead to subtle and frustrating bugs once one starts to customise their behaviour – especially if the rules on how they interact aren’t understood.

• Pygame 搞的视频合成器 - Python 作艺
  • art, sound, pygame

Critter and Guitari have built a bunch of insane video synthesizers that react to live music performance. They’re meant to enhance and automatically accompany a performance. Today, we’ll write a basic video synthesizer in Python, using aubio for Onset detection, and Pygame to display our graphics visually. We’ll end up with a program ready to be played out through a projector.

• Pandas 101: 索引
  • pandas

I’m going to go in depth a bit on two main concepts of Series & Dataframes. And then, what I found helpful in life, is becoming fluent in indexing dataframes.

(是也乎:

大坑...还是清洗时,针对最终输出嗯哼好就好 )

• Python 去 Go 作弊条儿
  • golang

For Python developer looking to get a taste of Go. Also do subscribe to http://importgolang.com/ to keep a track of Go Ecosystem.

(是也乎:

那什么,在这儿推荐这种是否... )

• CPython 内部探索
  • cpython

This is a quick guide for people who are interested in learning more about CPython’s internals. It provides a summary of the source code structure and contains references to resources providing a more in-depth view.

• JIT编译 Python子集到 x86-64
  • bytecode, JIT

This post shows how to write a basic JIT compiler for the Python bytecode, from scratch, using nothing but stock Python modules.

(是也乎:

scratch???

的确 bytecode 是个待挖掘的宝藏, 其实从这个环节进行静态化, 优化为毛不行呢?

• GitHub - tryolabs/requestium: 请求到 Selenium 之间的集成层，用于自动化web动作
  • Selenium, requests

Requestium is a python library that merges the power of Requests, Selenium, and Parsel into a single integrated tool for automatizing web actions. The library was created for writing web automation scripts that are written using mostly Requests but that are able to seamlessly switch to Selenium for the JavaScript heavy parts of the website, while maintaining the session. Requestium adds independent improvements to both Requests and Selenium, and every new feature is lazily evaluated, so its useful even if writing scripts that use only Requests or Selenium.

Selenium 坚持这么多年,终于熬死了其它前端测试框架统一江湖了啊啊啊啊啊 )

• 在5分钟内构建一个Python REST API – Python Rest API Toolkit
  • rest

In this post we introduce Arrested?—?A new framework for building REST APIs using Python. We’ll use Docker, SQLAlchemy, and other tools to build a Star Wars themed API in 5 minutes!

动用了 Docker 哪...

• 用Python分析1000多种希腊葡萄酒
  • scraping

In this post I'll play with the data I scraped from a Greek wine e-shop. In lieu of apology for sending a few more requests to their server I urge everyone browse through their catalog and maybe even buy a few bottles.

(是也乎:

分析希腊酒品质分布...

• 用深度学习预测加密货币价格
  • pandas, LSTM

We’ve collected some crypto data and fed it into a supercool deeply intelligent machine learning LSTM model. Unfortunately, its predictions were not that different from just spitting out the previous value. How can we make the model learn more sophisticated behaviours?

• 10 个Python 面试问题必知必会

  • interview, 面试经

• 如何使用 Pandas-DataReade r获得免费的当日期权数据

  • pandas

This is a simple reference article for readers that might wonder where I get/got my options data from. In this regard I would like to shout out the contributors to the pandas-datareader, without their efforts this process would be much more complex.

• JavaScript 的 Promises 等于 Python 的 asyncio
  • asyncio, js

JavaScript promises appear to be very different from Python's asyncio. But they're not that different! The code is written differently (the syntax is different), but what is happening under the hood is actually the same (the semantics are equivalent).

(是也乎:

这种姿势来蹭热点, 良心不痛嘛?

• 真正简单的方法来编写 Python 衰变函数
  • decay

At my exercise of reinforcement learning, I needed to write a decay function for ?-greedy strategy.

(是也乎:

decay ... 哈哈, 好形象 )

• 用Python 写个网格笔记纸张生成器

  • code snippets

• Testing Models with Django using Pytest and Factory Boy

  • django

Pytest and Factory Boy make a rad combo for testing Django Applications.

• pytest-annotate 开源鸟!
  • mypy, dropbox

Just a few days ago, Dropbox open-sourced PyAnnotate, a Python library that observes the execution of a Python program and automatically outputs Python type annotations. PyAnnotate greatly simplifies the process of using a type-checker (e.g. Mypy) with a legacy codebase.

老爹到了 Dropbox 后, 动作很多哪... 自动化类型声明补... )
