• 在N皇后问题上对比 Python, Go 和 C++ (PDF)
  • PASCAL FUA,
  • KRZYSZTOF LIS

"Python currently is the dominant language in the field of Machine Learning but is often criticized for being slow to perform certain tasks. In this report, we use the well-known N-queens puzzle as a benchmark to show that once compiled using the Numba compiler it becomes competitive with C++ and Go in terms of execution speed while still allowing for very fast prototyping."

• Codemodding Python: 将 Unittest 断言声明为 Python 断言
  • HANS-WILHELM WARLO

Large codebases require continued maintenance, but it is time-consuming and cumbersome to change portions of code scattered around many files. This article shows how to write codemods to refactor Python code using its Abstract Syntax Tree—gaining far more granular control than basic regex and search-replace.

• Arcade: Python 游戏框架入门
  • REAL PYTHON

In this step-by-step tutorial, you'll learn how to use arcade, a modern Python framework for crafting games with compelling graphics and sound. Object-oriented and built for Python 3.6 and up, arcade provides you a modern set of tools for crafting great Python game experiences.

• 创建一个简单的 Python Pip 存储库
  • JAN-PIET MENS

"I wanted the simplest (i.e. most lightweight) possible repository capable of serving packages in such a way as that Python's pip would be able to install them."

• 编写多语言脚本
  • NKANAEV.GITHUB.IO

Python and Ruby have somewhat similar syntaxes, could you come up with a program that's valid in both languages?
