前言 在本书开始时,我们努力展示了 Python 在当今数字调查中几乎无穷无尽的用例。技术在我们的日常生活中扮演着越来越重要的角色,并且没有停止的迹象。现在,比以往任何时候都更重要的是,调查人员必须开发编程技能,以处理日益庞大的数据集。通过利用本书中探讨的 Python 配方,我们使复杂的事情变得简单,高效地从大型数据...

而对于集合,其排序和前面讲过的列表、元组很类似,直接调用sorted(set)即可,结果会返回一个排好序的列表。 代码语言:javascript 代码运行次数:0 运行 复制 s = {3, 4, 2, 1} sorted(s) # 对集合的元素进行升序排序 [1, 2, 3, 4] 字典和集合性能 字典和集合是进行过性能高度优化的数据结构,特别是对...
