### Background One way to order a nested (reddit-style) commenting system is by giving each comment a rank. Generic comments on a thread start with rank 1 and increment, so the second comment on a thread would have rank 2. A reply to comment 1 will be ranked 1.1, and a reply to comment 1.1 will be ranked 1.1.1 . The second comment to reply to comment 1 would be ranked 1.2 . Note that since 1.1.1 is a valid rank, the ranks given are of type string. ### Task: Given a list of comment ranks (strings), order them as a comment thread would appear ### Assumptions: * there will always be a rank 1 in the given input * ranks are of type string * rank numbers are incremented, and not skippped (1.1 could be followed by 1.2, not 1.3) ### Example order: ``` [ '1', '1.1', '1.2', '1.2.1', '2', '3', '3.1', '3.1.1', '3.2' ] ```
sort_ranks=lambda li,A=lambda li:max(li,key=lambda x:(int(x.split(".")[0]),x)).split(".")[0]:sum([sorted([k for k in li if k.split(".")[0]==str(i)])for i in range(1,int(A(li))+1)],[])
