• Pyflyby: 提高 Jupyter 交互式会话效率
  • MATTHIAS BUSSONNIER
  • AND AARON MEURER

There’s a new tool in town that aims to improve Python developer focus and minimize distractions while coding, especially in Jupyter Notebooks. That new tool is pyflyby, and it can handle tidying up and collecting imports and exports from Python modules. For example, in a Jupyter Notebook, pyflyby can automatically import the right modules and functions from NumPy if you use something in a cell without importing it first.

• Copilot /用 Python 编写的文本游戏
  • SAGINDYK URAZAYEV

GitHub’s new Copilot feature has a lot of people talking. The project’s goal is to be an AI pair programmer — a tool that can suggest entire lines of code or even entire functions! In this amusing article, one developer who gained access to Copilot’s technical preview shares how the AI wrote an entire text-based adventure game that turned out to be the solution to an exercise from a Python instructional book.

• 更友好的 Tracebacks 在 REPLs (包含 Jupyter)
  • ANDRÉ ROBERGE

Tracebacks are often the start of any Python debugging journey. But tracebacks can be difficult to read and confusing to beginners. The friendly-traceback project aims to lift the veil of confusion for tracebacks by providing more helpful error messages with lots of context. New updates to the project include better tracebacks in Jupyter Notebooks!

'hello'

$ py log2 sys.maxint
[PYFLYBY] from numpy import log2
[PYFLYBY] import sys
[PYFLYBY] log2(9223372036854775807)
63.0

$ py 'plot(cos(arange(30)))'
[PYFLYBY] from numpy import arange
[PYFLYBY] from numpy import cos
[PYFLYBY] from matplotlib.pyplot import plot
[PYFLYBY] plot(cos(arange(30)))
<plot>
