1、
>>> a = list(range(1,11)) ## 生成列表 >>> a [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] >>> a[::-1] ## 倒序排列 [10, 9, 8, 7, 6, 5, 4, 3, 2, 1] >>> a [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] >>> b = [] >>> for i in reversed(a): ## 实现倒序排列 b.append(i) >>> b [10, 9, 8, 7, 6, 5, 4, 3, 2, 1]
2、在原列表上实现倒序排列
>>> a [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] >>> a.reverse() >>> a [10, 9, 8, 7, 6, 5, 4, 3, 2, 1]
