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,...
A standard order is called the ascending order: a to z, 0 to 9. The reverse order is called the descending order: z to a, 9 to 0. For dates and times, ascending means that earlier values precede later ones e.g. 1/1/2020 will sort ahead of 1/1/2021. Stable sort Astable sortis...

描述：虽然冒泡排序通常用于升序排序，但通过调整比较逻辑，也可以实现降序排序。只需将相邻元素比较时的大于号改为小于号即可。代码示例：pythondef bubble_sort_descending: n = len for i in range: for j in range: if lis[j] < lis[j+1]: lis[j], lis[j+1] = lis[j+1],...
