问题 I need to create a stored procedure in mysql that take some fields from DB and create a neasted json object: Firstly I create a json object as showing below: { "form": "Exams tests", "version": "v3.001.01", "questions": [] } And secondly a json array object like this: {[ { "ordem": 1, "num_questions": 1, "question1": "How old are you?"

问题 I want to create a datatable from this dataframe: df1 <- data.frame( brand = c("Brand 1", "Subbrand 1.1", "Subbrand 1.2", "Brand 2", "Subbrand 2.1", "Subbrand 2.2"), sales = 100 * 1:6 ) The brands should be parent rows and the subbrands child rows which should be hidden in the beginning. On click on a parent rows its subbrands should be shown. This must work without shiny as I want to integrate it into a HTML-flexdashboard. I think to solve this I will need a callback like in this example but

问题 This question already has answers here : Construct pandas DataFrame from items in nested dictionary (6 answers) Closed 2 years ago . I am calling an API that returns a batch request of multiple stock tickers in JSON format. It is a nested dictionary, with 2 levels of keys and then a list of dictionaries. Here is the script: import json import requests import pandas as pd r = requests.get('https://api.iextrading.com/1.0/stock/market/batch?symbols=aapl,wpx,mnro,twnk,labl,plnt,fsct,qyls,vrns

问题 I just started learning recursion and I have an assignment to write a program that tells the nesting depth of a list. Well, I browsed around and found working code to do this, but I'm still having trouble understanding how it works. Here's the code: def depth(L) : nesting = [] for c in L: if type(c) == type(nesting) : nesting.append(depth(c)) if len(nesting) > 0: return 1 + max(nesting) return 1 So naturally, I start to get confused at the line with the append that calls recursion. Does

问题 (In relation to this question I posed a few days ago) I have a dictionary whose keys are strings, and whose values are sets of integers, for example: db = {"a":{1,2,3}, "b":{5,6,7}, "c":{2,5,4}, "d":{8,11,10,18}, "e":{0,3,2}} I would like to have a procedure that joins the keys whose values satisfy a certain generic condition given in an external function. The new item will therefore have as a key the union of both keys (the order is not important). The value will be determined by the

问题 I have a nested relationship that I want to set a condition and a limit. $data = Accommodation::with('accommodationFacilities', 'city') ->take(10) ->with('accommodationRooms.roomPricingHistory') ->limit(2) ->where('is_deleted', 0) ->paginate(10); Now I have a nested relation on line 2 that I want to limit this relation by: roomPricingHistory . The code limits the parent relation which is: accommodationRooms . Any idea how I can limit the child relation and how can I set an if for it so if a

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
