❝ Life is pleasant. Death is peaceful. It’s the transition that’s troublesome. ❞— Isaac Asimov (attributed)‣ 显示目录概述#几乎所有的Python 2程序都需要一些修改才能正常地运行在Python 3的环境下。为了简化这个转换过程,Python 3自带了一个叫做2to3的实用脚本(Utility Script),这个脚本会将你...
In this paper, we describe a study that investigates the degree to which Python software developers are making the transition from Python 2 to Python 3. We have developed a Python compliance analyser, PyComply, and have analysed a previously studied corpus of Python applications called Qualitas. ...
In case you need to port your project from Python 2 to Python 3, you might consider using such hook during the transition period. First: $ pip install pre-commit and then in your project's directory: $ pre-commit install Next, you need to add this entry to your.pre-commit-config.yaml...
