nested

问题 I have a long list of nested tuples that I am iterating through and appending in a certain way such that an empty dictionary: dict = {} will be filled like this: dict = {a: {b:1,5,9,2,3}, b: {c:7,4,5,6,2,4}, c: {b:3,13,2,4,2}... } The iteration will check if a nested dictionary exists, and if so, then it will append the value, otherwise, create a nested dictionary. My poor attempt looks something like this: longlist = [(1,(a,b)),(2,(b,c)), (3,(c,b)) ... ] dict = {} for each in longlist: if

问题 Given this tables: BOOKS id | data ----+------------------------------------------------------- 1 | { title: 'Book 1', price: 10.5, authors: [{ id: 1}, { id: 2 }]} 2 | { title: 'Book 2', price: 11.5, authors: [{ id: 2 } } AUTHORS id | data -----+------------------------------------------------------- 1 | { name: 'Author 1', address: 'Address author 1' } 2 | { name: 'Author 2', address: 'Address author 2' } Is it possible to obtain this result, by merging the authors key array elements, with a

问题 I have a case in which a Java class has a superclass that contains a synchronized block. Class SuperClassA { private Bitmap bmpA; protected abstract Bitmap createBitmap(); public void run() { synchronized (this) { bmpA = createBitmap(); } } // some other codes. } Class SubClassB extends SuperClassA { private Bitmap outBmpB; protected Bitmap createBitmap() { outBmpB = ..... // create and process "outBmpB".

问题 I'm running into an issue with nested menus not acting the way I'm anticipating. I've looked through a bunch of stuff on StackOverflow regarding stopPropagation(), but it just doesn't seem to be working. The site is wordpress based, unfortunately, so I don't have direct control of the HTML generated by the menus on the site. The original goal of this project was to add onClick functionality to the menu items, which Wordpress doesn't natively support. That part works - when I click the menus,

问题 I need to have a ng-click-event nested into another ng-click-event. This doesn't seem to be a problem in the Chrome client I am able to use here at work, but the standard browser is IE9. The problem is that clicking on the inner control does not trigger the function corresponding to the inner control, but rather the function of the parent control. The code looks a little like this: angular.module('App', []) .controller('Controller', function() { var self = this; self.outer_function = function

问题 This question already has answers here : Iterate through Nested JavaScript Objects (13 answers) How can I access and process nested objects, arrays or JSON? (23 answers) Closed 6 years ago .

问题 I want the program to ask each of the five players the seven questions, calculate the player score and then display a list of each players score eg Points for week 1 player1 43 player2 26 player3 38 etc etc Then ask the players the questions again and do the same for week 2. Currently the program will only display the first players score, then ask the questions to all five players again but only display the second players score, it repeats this five times while only iterating through the

问题 I have a rails app where users create projects . Currently these are nested, and are completed as separate actions (A user registers, and then from the project dashboard creates a new project ). To improve conversions (as well as track conversions from adwords and facebook) I want to create a new view called getting_started whereby a user will register and create a project in one step from a single view. In terms of best practice, should I create a new controller for this, rather than just
