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.


任何概念深了说, 都不怎么平易


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.





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.

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.

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



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?


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 )

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...


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.





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?

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 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).


这种姿势来蹭热点, 良心不痛嘛?

promises 那是被逼的, 在 py3 是原生的





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


decay ... 哈哈, 好形象 )

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

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.
