sorting

问题 Currently on my project I am trying to sort the rows of a CVS sheet by a singular column, I am using PANDAS and I have seen several examples posted all around the internet, however when trying to implement this myself I have been unable to. db = pd.read_csv(databasefile, skip_blank_lines=True, names=['ExampleOne','ExampleTwo','ExampleThree','ExampleFour'], header=1) db.drop_duplicates(inplace=True) db.sort_values(by=['ExampleOne'], ascending=[True]) db.to_csv(databasefile, index=False) In the

问题 This question already has answers here : How to sort a list of strings numerically? (14 answers) Closed 8 months ago . I am trying to sort a text file in numerical order, from largest at the top of the file, to lowest at the bottom of the file. Each line in the file only contains one number. I want to know how I can sort the text file every time run the code so that the numbers are always sorted. This is then used so I can then make a leaderboard. savefile.write("\n") savefile.write(User1)

问题 This question already has answers here : 400x Sorting Speedup by Switching a.localeCompare(b) to (a<b?-1:(a>b?1:0)) (5 answers) Closed 1 year ago . Im sorting an array of objects alphabetically but not sure which way is more efficient. Im currently using the .sort() method and its working fine but would using the localeCompare() be a better alternative? 回答1: The localeCompare function is absurdly slow on many browser. Avoid it if possible. The other locale functions are really bad too,

问题 I import an Excel-spreadsheet using the following SAS-procedure. %let datafile = 'Excel.xlsx' %let tablename = myDB proc import datafile = &datafile out = &tablename dbms = xlsx replace ; run; One of the variables ( date_variable ) has the format DD.MM.YYYY. Therefore, I was defining a new format like this: data &tablename; set &tablename; format date_variable mmddyy10.; run; Now, I would like to sort the table by that variable: proc sort data = &tablename; by date_variable; run; However, as

问题 I am working on a sortable table. Every column has a button for giving each row a respective data-position value. For example, by clicking on a button for sorting rows in ascending order by alphabet I can assign datasets from 1 to n to each of those rows. When I click another button to sort by another parameter, I reassign those datasets. The only issue now is that my rows stay at one place and don't change their positions. I assume I could do it with CSS positioning but not sure how. Here is

问题 (I use Java) I want to sort a sublist of objects by a property using a Collator so that is sorted by alphabetical order but ignoring accents. Problem is I have tried different things and none work. This sorts the sublists but doesn't ignore accents: newList.subList(0, 5).sort(Comparator.comparing(element -> element.getValue())); This is the collator I want to use: Collator spCollator = Collator.getInstance(new Locale("es", "ES")); I expect the output to be a sublist sorted by alphabetical

问题 I have an array of objects that also contain IDs like so: const arr = [ { id: "5ffca1c771138d181c3bde0b", otherValue: 10 }, { id: "5ffca1c771138d181c3bde0e", otherValue: 3}, { id: "5ffca1c771138d181c3bde12", otherValue: 7}, { id: "5ffca1c771138d181c3bde04" otherValue: 1}, { id: "5ffca1c771138d181c3bde08", otherValue: 11} ] I then have second array, that contains a subset of the IDs of the first array in a particular ordering, like so: const arrIds = [ "5ffca1c771138d181c3bde12",

问题 I want to sort this javascript array: [103,3,4,6,8,"8L",67,1,11,19,68,86,107,"9L"]; sort it by numbers and letters, so the result will look like this: [1,3,4,6,8,"8L","9L",11,19,67,68,86,103,107]; When I try to use sort() , it doesn't work: [1,3,4,6,8,68,103,"8L",11,19,67,86,107,"9L"]; // 8L and 9L are in the wrong place // correct wanted order var correct = [1,3,4,6,8,"8L","9L",11,19,67,68,86,103,107]; document.body.innerHTML += '<b>correct wanted order:</b> <pre>' + JSON.stringify(correct)

问题 I am coding a number of forms (possibly ultimately many dozens, all variants of one main template) into separate flat databases. Each form has over 2 - 300 fields that are unique entries. After assigning range names to all these fields, when I get a list of Range Names using the Formulas->Use in Formula->Paste Names->List , I get all the Named Ranges but they are sorted alphabetically. I need these in the order they appear in the Data Entry Form, sorted by row, then column. By using the Right

问题 Because I'm using Nativescript I'm using the same Typescript code for Android and iOS. I have a very large data set of about 1000-2000 (could be bigger) objects with very large data values in an array. const unsorted = [ ..., { name: "name1", value: 10000000 },{ name: "name120", value: 200000000 },{ name: "name42", value: 3 },{ name: "name1203", value: 1000000000000 }, ... ]; const sorted = unsorted.sort((a,b) => (b.value-a.value)); On Android, sorted is always correctly sorted, but iOS is
