1、Python List reverse()方法 reverse() 函数用于反向列表中元素。 >>> a = [1,2,3,4,5] >>> a.reverse() >>> a [5, 4, 3, 2, 1] 语法: 'sep'.join(seq) 参数说明 sep:分隔符。可以为空 seq:要连接的元素序列、字符串、元组、字典 ...
7.how do I iterate over a sequence in reverse order for x in reversed(sequence): … # do something with x.. 如果不是list, 最通用但是稍慢的解决方案是: for i in range(len(sequence)-1, -1, -1): x = sequence[i] 8.Python是如何进行类型转换的?

l=list(s)## 列表翻转 l.reverse()##将列表中的数字逐个输出,组合成字符串 s=''foriinrange(len(l)):s=s+l[i]print(s) 以上就是python反向输出数字的方法,本篇的输出数字和列表的操作密不可分,建议大家先对列表模块的内容有所掌握,再回过头学习反向输出数字的操作。
