dictionary

问题 I've got an JSON string from my API, looks like this: [ { "id": "abc", "data": { "Name": "Peter", "Date": "2017/12/01" } }, { "id": "def", "data": { "Name": "Tina", "Date": "2017/12/20" } }, { "id": "ghi", "data": { "Name": "Amy", "Date": "2017/12/16" } } ] Then, I use (java): Gson gson = new Gson(); Type resultType = new TypeToken<List<Map<String, Object>>>() { }.getType(); List<Map<String, Object>> result = gson.fromJson(info, resultType); if I call result.get(0).toString()); then it

问题 What i'm trying to do here is to make a loop to create multiple graphs of dicts. I looped to execute univariate rolling window regressions and I stored the COEFS and the R_SQ of each variable in a DICT. the DICT itsel got 23 sub DICT each containing my a series of coefficients and rsquareds from 2008 to 2020 (4580 obs.) It goes like this (for visualisation): data1 BE10USD params - const & coef r_sq BE30CAD params - const & coef r_sq SWAP1YUSD params - const & coef r_sq And on, my dict is

问题 Im trying to do Pagination with MongoDB I write this code: findOptions := options.Find() findOptions.SetLimit(20) findOptions.SetSort(bson.M{{"_id", 1}}) cursor, err34 := collection.Find(context.Background(), bson.M{{"_id", bson.M{{"$gte", last_id}}}}, findOptions) Now It keeps complaining: missing type in composite literal go AND missing key in map literal go It complains for this part: findOptions.SetSort(bson.M{{"_id", 1}}) and bson.M{{"_id", bson.M{{"$gte", last_id}}}}, findOptions) I'm

问题 I have a table column, that contain description of the treatment done to resolve an issue, this text contian keywords. In other list, I have the list of categories, with the different keywords that helps to identify it. For example: Category | keywords AAAA | keyword1 AAAA | keyword2 and keyword3 AAAA | keyword3 and not keyword4 BBBB | keyword4 BBBB | keyword5 and keyword6 BBBB | keyword7 how can fill the category column in my previous table (that contain the description), using the keywords

问题 I have a pandas dataframe that I would like to pull information from and create a nested dictionary for downstream use, however, I'm not very good at working with pandas yet and I could use some help! My dataframe looks something like this: Sequence A_start A_stop B_start B_stop 0 sequence_1 1 25 26 100 1 sequence_2 1 31 32 201 2 sequence_3 1 27 28 231 3 sequence_4 1 39 40 191 I want to write this to a dictionary so that it has this form: d = {‘Sequnce: {(‘A_start’, ‘A_stop’) : [{'repeat

问题 I have a list like this: mylist[1:3]=[{'Keywords': 'scrum master', 'result': {'categoryId': '3193', 'categoryName': 'agile coach', 'score': '1.0'}, 'categoryId': '3193'}, {'Keywords': 'principal consultant', 'result': {'categoryId': '2655', 'categoryName': 'principal consultant', 'score': '1.045369052886963'}, 'categoryId': '2655'}, {'Keywords': 'technicalfunctional consultant', 'result': []}] I want to run the following code: categories=set(x['result']['categoryName'] for x in mylist) It

问题 I'm a beginner C++ programmer so there are language constructs that I don't understand which prevents me from understanding map's API (for your reference, here) More to the point, some questions: How do I change the internal sorting scheme of map so that, given that we're working with map::<string, ...> , the key values are sorted alphabetically? More specifically about the map::key_comp , is it a define-and-forget thing where once we define what it means for two elements of the same type to

问题 I'm trying to make an API to create custom maps on a game I made, but shelve just writes blank lists and dictionarys. I try to store it like that: "name" for the shown name of the map "name_1" for the name that is treated as variable "textures" for the filepath of the texture "wind" for the amount of wind that's blowing Heres my code: import tkinter.filedialog as tfd import shelve import shutil as os file1 = shelve.open("info") if "written" in file1: pass else: file1["name"] = [] file1["name

问题 Background: I have a dictionary diskInfo with key as string and value as dictionary of type string, double. For each entry into the foreach loop, I calculate the disk space and store the result into spaceInfo dictionary. This is then passed on to be stored as the value for corresponding key in diskInfo dictionary. Problem Each time I clear existing entries in spaceInfo and readd the key value pairs before storing into diskInfo dictionary. At the end of the loop, diskInfo dictionary has keys
