问问可爱吧友,这道P..string = input('Enter string :')while string != '#':s=list(string)s.sort()s.reverse
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.You’ll cover the optional arguments key and reverse later in the tutorial.The first parameter of sorted() is an iterable. That means that you can...

sorted(iterable, key=None, reverse=False) iterable:要排序的可迭代对象。 key(可选):一个函数,用于从每个元素中提取比较键。 reverse(可选):如果为 True,则降序排序;默认为 False(升序)。 示例 python numbers = [3, 1, 4, 1, 5, 9, 2, 6] sorted_numbers = sorted(numbers) print(sorted_numbers...

升序排序：直接调用 sort 方法，不传递 reverse 参数或将其设置为 False。pythonmy_list = [5, 2, 9, 1, 5, 6]my_list.sort # 升序排序，默认行为print # 输出: [1, 2, 5, 5, 6, 9] 降序排序：将 reverse 参数设置为 True。pythonmy_list = [5, 2, 9, 1, 5, 6]my_list...
//看下面的python代码: //=== //for i in a : // print i //=== //还有就是,通过each()我很循环的时候这个i,是当前数组的"索引"(这里和python中不同) //所以要获取内容的时候a[i]就是获取当前的内容 } 现在我们循环他然后通过ID找到对应的input的标签然后把值付给他。 //当点击时从form表单...
