A custom key function can be supplied to customize the sort order, and the reverse flag can be set to request the result in descending order. 相同点: sort 和 sorted 都有两个可选仅限关键字参数 key 和 reverse,都是默认升序排序。 不同点: 1.sort 是列表的一个方法,它的第一个参数是 self,...
reverse flag can be set to request the result in descending order. 像操作列表一样,sorted()也可同样地用于元组和集合: >>> numbers_tuple = (6, 9, 3, 1) >>> numbers_set = {5, 5, 10, 1, 0} >>> numbers_tuple_sorted = sorted(numbers_tuple) >>> numbers_set_sorted = sorted(numb...
如果尝试在包含不可比较数据的列表上使用sorted(),Python将返回错误。在此示例中,由于不兼容性,无法对同一列表中的None和int进行排序: >>>mixed_types=[None,0] >>>sorted(mixed_types) Traceback (most recent call last): File"<stdin>", line1, in<module> TypeError:'<' not supported between instance...

前面我们看到的利用key-function来自定义排序,同时Python也可以通过operator库来自定义排序,而且通常这种方法更好理解并且效率更高。 operator库提供了 itemgetter(), attrgetter(), and a methodcaller()三个函数 >>>fromoperatorimportitemgetter,attrgetter
In Python, sorting data structures like lists, strings, and tuples can be achieved using built-in functions like sort() and sorted(). These functions enable you to arrange the data in ascending or descending order. This section will provide an overview of how to use these functions. ...
