1.首先，定义了一个名为 numbers 的列表，其中包含了五个整数元素。sorted_descending = sorted(numbers, reverse=True)在这里，我们使用 sorted 函数对 numbers 列表进行排序，并设置了 reverse 参数为 True。2.通过将 reverse 参数设置为 True，我们告诉 sorted 函数按照降序排序。这意味着元素将按照从大到小的顺...
>>>s =sorted(student_objects, key=attrgetter('age'))# sort on secondary key>>>sorted(s, key=attrgetter('grade'), reverse=True)# now sort on primary key, descending[('dave','B',10), ('jane','B',12), ('john','A',15)] 传统的DSU(Decorate-Sort-Undecorate)的排序方法 传统的DSU(...
sorted() __sorted 还可用于按指定条目排序。简单来说,比如排序一个二维数组,可指定按照array[x][1]排序__ 具体请参考: "Python sorted() 函数" sort() 参考: "Python List sort()方法"
