Instead, python reads the machine code in as a bytearray of shellcode where the binary data is represented by a hex value where the \x represents the offset. (是也乎: ASM … ) pythonbooks.org books Discover the best books in every Python book category. (是也乎: 太实用了…当然的, 没有一本中国原创的. ) 用 Hydrogen 进行交互 IDE Hydrogen is a package for Atom editor that allows interactive programming in different languages. I would call it a bridge, or even a sweet spot, between Jupyter Notebooks and a full blown IDE (like IntelliJ IDEA). (是也乎: 桥件,能将 Jupyter 和 IDE 粘合起来 ) 深入 Closures 和 Decorators - 第一部分 closures 使用进程池加速您的Python数据处理脚本 futures With the concurrent.futures library, Python gives you a simple way to tweak your scripts to use all the CPU cores in your computer at once. Don’t be afraid to try it out. Once you get the hang of it, it’s as simple as using a for loop, but often a whole lot faster. (是也乎: 问题是前提,你的数据是可原子切分处理的 ) 设置 Sublime Text 3 为 Python 进行类型检查 sublime GANs N’ Roses machine learning Imagine one day wherein we had a neural network which could watch movies and generate it’s own movies, or listen to songs and compose new ones. This network would learn from what it sees and hears without you explicitly telling it. This way of letting a neural network learn is known as unsupervised learning. (是也乎: 无监督学习系统的嗯哼 ) PyPy 究竟是什么? pypy PyBay 奖学金计划发布 conference In the spirit of increasing the Python community’s inclusivity and diversity, PyBay is pleased to announce this year’s conference scholarships. Our scholarships are designed to support members of our community for whom attending PyBay would present a financial challenge. 开始 Jupyter Notebook 的5个最佳技巧 jupyter We’ve discussed a few reasons to use Jupyter Notebooks as a GIS user. From visualization of your data to the recent integration with the ArcGIS platform, Jupyter Notebooks are quickly becoming a crucial component of GIS and data science workflows. In spite of these benefits, coming up to speed and getting comfortable with Jupyter Notebooks can be a daunting task for a new user. There is nuance to the way Jupyter Notebooks operate that can take some time to comprehend. (是也乎: 简单的说 ipynb 不是 IDE 也不是编辑器, 而是一个能方便的记录并同时积累我们思考的环境 ) 机器学习和深度学习工程师的基础作弊书 machine learning CheatSheets for Pandas, numpy etc. collections.Counter - Weekly Python Chat counter You want to count the number of times each thing occurs in your list. How do you do it? We’ll talk about the many ways to solve this problem, concluding with the most Pythonic way: Counter. scrapy 中的 404 链接检测器 code snippets 高级 Python 功能 core-python 好物 ~ 包/模块/库/片段… ...

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. (是也乎: 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. 几个俺开始用的新工具 curated list Note - Two, to be precise. Wasn’t aware of python-gist myself. 月度 PyPI: IPython, pytest, cryptography 和 NumPy pypi Monthly PyPI digest. 用 Python 和 Flask 进行图像上传和审核 flask Almost all applications contain images. Image moderation has become a necessity. We will see in this article how to moderate your images automatically. (是也乎: 基于 Realtime image moderation and nudity detection API - Sightengine 进行鉴黄… ) 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. (是也乎: 看起来很复杂, 但是, AWS 就是这样将元能力嗯哼好, 大家就可以自在的组合成各种嗯哼… ) 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. (是也乎: 冲这么嗯哼的 logo 就可以尝试了.. ) 使用 PyFolio，R 的 PerformanceAnalytics 和 backtrader 进行股票交易分析优化 stock trading Curator - If you ever dreamed of writing code that makes you money while you sleep or are relaxing on a beach. On a serious note this is a solid blog post on stock reading Stock Performance analytics. 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.

Not only has Instagram scaled to become the biggest Python user in the world, but the company recently moved over to Python 3 with zero user experience interruption. Instagram engineers Hui Ding and Lisa Guo talked with The New Stack to share the Python love and describe the Python 3 migration experience. (是也乎: 简单的说…没那么简单. ) Twitter 上的 NLP 广告数据 NLP I chose to perform Natural Language Processing (NLP) on Twitter data in order to assist in advertising campaigns. This project is geared more towards advertisers, marketing, and any company who wants to extend their customer relations platform to communicate with their followers. (是也乎: 简单的说, 只有商业成功的技术方案才有权力继续嗯哼… ) 用 uWSGI 在 Docker 部署迷你 Python docker So, you’ve built a great Python web application using Flask, Django, aiohttp, or Falcon. The next issue you could be facing is probably the setup regarding the deployment. We will explore how to use docker-compose to deploy a WSGI application using uWSGI and NGINX. (是也乎: 简单的说, 还是离开不能 NGNIX ) A good way to lose an afternoon reading about Python’s internals tweet TDD 课程 - By The RealPython Folks tutorial In this tutorial, you’ll learn how to quickly spin up a reproducible development environment with Docker to create a RESTful API powered by Python, Postgres, and the Flask web framework…. 极端 Lazy 来并行 Python 函式 codesnippet 用 Python 检验伪影片 codesnippet Program to detect if there are any loops in the video. 用 Python 来折腾音频信号 codesnippet Now it comes as a surprise to many people when I tell them that generating an audio waveform is extremely simple.

That’s how I got interested in Google Analytics API. As I am studying Data Science at the moment, knowing how to do web analytics would open up a lot of new possibilities. (是也乎: 简单说就是配置过程太复杂了… ) Python 填字游戏拼图生成器 codesnippet Python Requests 构建 codesnippet Epithet github Introducing Epithet, a Python-based command line tool for managing labels across an organization. You give it a Github key, organization, and label name, and it will make sure that label exists across all the repos in your org. Give it a color, and it’ll make the color of that label consistent across all repos as well. Have you decided you’re done with a particular label? Epithet can delete it from all your repos for you. Are you using Github Enterprise? Epithet supports that too. (是也乎: 又一个 CLI 工具, 通过标签来管理组织的仓库… 哈. ) 搞笑 - Python 私有方法 humor (是也乎: ) RC Car + MacBook Pro = The Carputer! arduino If you’d like to build a miniature self-driving car, perhaps you would first turn to an Arduino for control or even a Raspberry Pi for more advanced processing. Otavio Good is no exception, but after attaching a few Arduinos to an RC car, he moved on to driving it with a speedometer and camera via a TensorFlow neural network running on a Macbook Pro?—?yes, it has an actual notebook computer embedded in the 1/10th-scale model car.
