应用:要是想要找两个列表的公共元素,那么可以先将它们转成set,然后求交,或者找到两个列表中不同的元素,那么先转成set,然后求差,set中不能出现重复元素这个特定也很好用,有时候可以直接用添加,因为set可以自行判断元素是否重复。

一种需要在字段上添加类型提示的替代方法——自 Python 3.5 起,3.6 中添加了class语法。 @dataclasses.dataclass 一个类装饰器,允许比以前的替代方案更多的定制化,增加了许多选项和潜在的复杂性——自 Python 3.7 起。 在讨论完这些类构建器之后,我们将讨论为什么数据类也是一个代码异味的名称:一种可能是糟糕面向...

popitem() is useful to destructively iterate over a dictionary, as often used in set algorithms. If the dictionary is empty, calling popitem() raises a KeyError. Changed in version 3.7: LIFO order is now guaranteed. In prior versions, popitem() would return an arbitrary key/value pair. ...
