在 Python 中如何创建只读属性和限制性值对象

用 Python 进行异步抓取

Scraping is often an example of code that is embarrassingly parallel. With some slight changes, our tasks can be done asynchronously, allowing us to process more than one URL at a time. In version 3.2, Python introduced the concurrent.futures module, which is a joy to use for parallelizing tasks like scraping. The rest of this post will show how we can use the module to make our previously synchronous code asynchronous.

lptrace
- opensource project

lptrace is strace for Python programs. It lets you see in real-time what functions a Python program is running. It's particularly useful to debug weird issues on production.

Python 的静态类型,嚓 my(py)!
- mypy

In this post, I’ll explain how mypy works, the benefits and pain points we’ve seen in using mypy, and share a detailed guide for adopting mypy in a large production codebase (including how to find and fix dozens of issues in a large project in the first few days of using mypy!).
