• Fire 介绍 - 能自动生成 CLI 的嗯哼 - By Google
  • CLI

Today we are pleased to announce the open-sourcing of Python Fire. Python Fire generates command line interfaces (CLIs) from any Python code. Simply call the Fire function in any Python program to automatically turn that program into a CLI. The library is available from pypi via pip install fire, and the source is available on GitHub.

(是也乎:

文档在 google/python-fire: Python Fire is a library for automatically generating command line interfaces (CLIs) from absolutely any Python object.

• 用 Python 3.6 类型提示编写更好软件
  • type annotations

Type annotations are a precious tool (especially if used in combination with an advanced IDE like PyCharm) that allow us to: write clear and implicitly documented code, prevent us from invoking methods with wrong data types (ok, actually we can do whatever at runtime since Python is a dynamic language and type hints as the name suggests is just that: an hint) and get useful code suggestions and autocompletion.

• 用 Facebook 的 Prophet Library 预测网站流量
  • machine learning, forecasting

I was very interested to see that Facebook recently open sourced a python and R library called prophet which seeks to automate the forecasting process in a more sophisticated but easily tune-able model. In this article, I’ll introduce prophet and show how to use it to predict the volume of traffic in the next year for Practical Business Python. To make this a little more interesting, I will post the prediction through the end of March so we can take a look at how accurate the forecast is.

• 俺的经验: 基于长运行时 芹菜 发布的微服务
  • celery

While Celery is well-maintained, it’s not easy to find examples of advanced patterns of real-world usage. Also it’s often been difficult to find solutions to issues that we’ve come across. So I want to share some of our experiences.

  • microservices Nowadays it is a common practice to work in smaller applications, sharing the responsibility among many different services. I believe it is critical to have some standard tools between the teams working solving those problems.

  • scraping

Postmates regularly does promotions where they offer free food and waive the delivery fee for certain restaurants. I recently realized that I could make this simpler by creating something that would track the Postmates website and notify me of deals.
