问题 I am having trouble with some variable types in my code. The error that I get now is: TypeError: can't convert type 'str' to numerator/denominator The code line in question is the following: valor_anual[data[0]['Dados'][json_date][0]['geodsg']][year_code] = statistics.mean(valor_mensal_aux) Here is a snippet of my code to give you guys context: valor_anual = [0][0] for city_code in city_codes: for year_code in year_codes: valor_mensal_aux = [] for month_code in month_codes: url_imob = Request

问题 ,"people" : { ".read": "auth != null", "$uid": { }, "e2" : { ".read": "auth.uid != null", ".write": "$uid == auth.uid" }, "l1" : { ".read": "auth.uid != null", ".write": "auth.uid != null" } So e2 is the @ of an email. For example @gmail or @aol or @yahoo. For the l1 child, I want to make the write rule: Write if auth.uid != null && e2 has the same value as the e2 of the person you are writing l1 to. The furthest I could get, is something like this: "data.parent().child(people).hasChildren([

问题 I'm trying to style my renderItem in FlatList but elevation not working properly. Is there anything I'm wrong or this is a React Native issue? I tested ListView too but it still not working properly This is TodoItem component import React, { Component } from 'react' import { Text, View, StyleSheet } from 'react-native' const styles = StyleSheet.create({ container: { height: 60, backgroundColor: 'white', borderRadius: 10, shadowColor: '#000', shadowOffset: { width: 2, height: 2 },

问题 I'm struggling with memory management or correct usage of object oriented Fortran 2008. My code has multiple derived types with the same parent (here Example01 and Example02 ) stored in a Example_Class module. I want to load one example in a subroutine workenv depending on some variable (here idx_example ). Whichever one is chosen should be accessed by procedures defined in the base class, so I can do call active_Example%Info() regardless of what active_Example is. The following code compiled

问题 I have the current JSON "updateTime": "2021-02-12T16:41:21.413Z", "dueDate": { "year": 2021, "month": 2, "day": 17 }, "dueTime": { "hours": 4, "minutes": 59 }, ... How can I retrieve the values of dueDate and dueTime (including all of the data in the dictionary) using Swift? Thanks in advance 回答1: My suggestion is to decode the JSON with Decodable into structs and join the date and time parts to a DateComponents instance let jsonString = """ { "updateTime": "2021-02-12T16:41:21.413Z",

问题 I am trying to cast a list of objects within a consturctor for a derive class IntersectionPath as follows. public class IntersectionPath : Path<IntersectionSegment>, IEnumerable { //Constructors public IntersectionPath() : base() { Verts = null; } public IntersectionPath(List<Intersection> inVerts, List<Segment<Node>> inEdges) : base() { this.Segments = (List<IntersectionSegment>) inEdges; } } Segments is defined in the generic base class Path public class Path<T> : IEnumerable<T> where T :

问题 I tried using a web app that would access h20 flow using REST API routes and when I tried to delete a frame (it would delete the frame after predicting), this happens: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://139.59.249.87:54321/3/Frames/1i3uso. (Reason: CORS header 'Access-Control-Allow-Origin' missing). I'm using ruby rails in order to build the web app. Any advice? I used this route: DELETE /3/Frames/{frame_id} and this coffee

问题 I think I'm missing something simple, but I can't find any examples showing how to do this... also, please forgive me if some of the terminology I'm using is wrong. I simply want to use an HTML form that is bound to a Kendo Observable object to create a new record in my remote datasource. All the examples I've seen show how to edit existing records, but that's not what I'm looking for (at least not at the moment). I've created a Fiddle http://jsfiddle.net/matbeard/fYfYz/2/ with a simple cut
