leetcode 937 求助 python

test cast 是这样的：Input: logs = ["dig1 8 1 5 1","let1 art can","dig2 3 6","let2 own kit dig","let3 art zero"]
Output: ["let1 art can","let3 art zero","let2 own kit dig","dig1 8 1 5 1","dig2 3 6"]


给出的解法都是sort log.split()[0]？？？
我不懂了，要是log信息是 dig12， sort会排到dig2前面啊？？？？难道题面上只是一位么？我没找到啊

amazon oa里sort log.split()[0]也能过么？

谢谢各位

好吧，是我想多了，只说了是 identifier 并没说具体规则
