The Python implementation of the set data structures uses ahashtableas its underlying data structure. This explains the O(1) membership checking, since looking up an item in a hashtable is an O(1) operation, on average.It does a direct lookup to access an element. ...
数据结构(Data Structures)基本上人如其名——它们只是一种结构,能够将一些数据聚合 在一起。换句话说,它们是用来存储一系列相关数据的集合。 Python 中有四种内置的数据结构——列表(List)、元组(Tuple)、字典(Dictionary)和集合(Set)。我们将了解如何使用它们,并利用它们将我们的编程之路变得更加简单。
