问题 I would like to sort a list in Python based on a pre-sorted list presorted_list = ['2C','3C','4C','2D','3D','4D'] unsorted_list = ['3D','2C','4D','2D'] Is there a way to sort the list to reflect the presorted list despite the fact that not all the elements are present in the unsorted list? I want the result to look something like this: after_sort = ['2C','2D','3D','4D'] Thanks! 回答1: In [5]: sorted(unsorted_list, key=presorted_list.index) Out[5]: ['2C', '2D', '3D', '4D'] or, for better

问题 I have a named list of term frequencies, > list $`in the` [1] 67504 $`to the` [1] 36666 $`of the` [1] 79665 $`on the` [1] 31261 $`to be` [1] 25862 $`for the` [1] 28332 I want to sort them into descending order according to the frequencies. How to do this? I tried sort, sort.list, order but had errors saying they don't accept this type of list. 回答1: You can try by unlist and then use order lst[order(unlist(lst),decreasing=TRUE)] # $`4` #[1] 9 #$`3` #[1] 7 #$`1` #[1] 5 #$`2` #[1] 4 #$`5` #[1] 2

问题 I have a tableview, its header is stored in a mutablearray, the array looks like (2005 fall, 2005 spring, 2007 summer...)

The output in this example should be: A=['1','2','3','4','5','67'] . Another example: s='25' A=['1','2','3','4','5','6','7'] output: A=['1','2','34','5','67'] Is there a way of doing this without any import statements (this is so that I can get a better understanding of Python

问题 I'm having issues using sort in VBA. I saw this thread for which the answers don't work for me : Sort in VBA I believe there is a maximum nr of records on which you can sort. Is that correct?
