• PEP 698: 覆盖静态类型的装饰器
  • PYTHON.ORG

This Python Enhancement Proposal describes the use of a new decorator, @override, which would be used as a type-hint for methods in a sub-class that override a parent’s method.

不觉中蟒周刊快译已经到了第11个年头

开始有小伙伴加入承担 pythonisa 周刊的翻译, 从来没提醒过, 可就这么默默坚持下来了...

问为什么:

[皱眉]每周新闻资讯 怎么能错过 
看看有什么新东西 
当有新的发现时：
    what f**k 还能这样玩？ 还有这东西？
    每周开彩蛋[吃瓜]

无法同意更多... 很多社区贡献看起来辛苦, 其实受益最多的, 就是主动承担者也.
