按每个int的第一位对int列表进行排序 [英] Sort list of ints by the first digit of each int

问题描述

我试图弄清楚如何按每个int的第一个数字对整数列表进行排序(如果相同，则移至下一个数字，依此类推)

I'm trying to figure out how to sort a list of integers by the first digit in each int, (and if the same, move to the next digit, etc.)

我确定我可以循环遍历，(尽管我一直遇到问题，因为为了获取第一个数字，我似乎需要将我的列表包含在字符串列表中，但这一直没有起作用但我想知道是否有一种方法可以通过sorted()方法轻松地做到这一点.

I'm sure I can just loop through, (although I've been having issues because it seems like I need to make my list a list of strings in order to grab the first digit and this just hasn't been working out for me), but I'd like to know if there is a way to do this easily with the sorted() method.

EX:

myList = [34254, 2343, 49, 595, 323]

我想要的结果:

sortedList = [2343, 323, 34254, 49, 595]

推荐答案

使用一串字符串进行排序，您将获得ASCIIbetical排序.

Sort with a key of strings and you'll get ASCIIbetical sorting.

>>> myList = [34254, 2343, 49, 595, 323]
>>> sorted(myList, key=str)
[2343, 323, 34254, 49, 595]
