• 几个 Python 3 决择 / 进化 的关键视图
  • core-python

The people who introduced me to Python chose it because of the elegance of the language, and it's aesthetic qualities. Would they choose it again, I wonder? Would I?.

是什么以及为什么的 Py3

def hello_world(name):
    print 'Hello', name

-->

@coroutine
async def hello_world(name: str) -> str:
    await print('Hello {}'.format(yield from name))

一定是太多 C++ 程序媛进入了 python 内核开发团队! )

• 使用 Uber 的 Pyflame 和日志解决问题
  • debugging

This time, it was different though. My distributed web crawler seemed to be slowing down over time. Adding more nodes only had a temporary performance boost; the overall crawling speed gradually declined afterwards. So simply put, it couldn't scale. But why?. In this post, you'll find out what techniques and tools I used to diagnose scaling issues - and to an extent, more general performance issues - in my Python-based web crawler.

• Python Packaging 简要指南
  • packaging

Code reuse is a very common need. It saves you time for writing the same code multiple times, enables leveraging other smart people’s work to make new things happen. Even just for one project, it helps organize code in a modular way so you can maintain each part separately. When it comes to python, it means format your project so it can be easily packaged. This is a simple instruction on how to go from nothing to a package that you can proudly put it in your portfolio to be used by other people.

• 类型跟踪对Python很有用
  • debugging

Type Tracing - as a program runs you trace it and record the types of variables coming in and out of functions, and being assigned to variables.
