object

问题 I am working on a game as a side project for fun and I have run into this error and I really don't know why it is happening... Here is the code: class players: def __init__(self, location, image_file, direction): self.location = location self.image_file = image_file self.direction = direction self.rect = self.image_file.get_rect() def turn(self, direction, playerImages): keys = pygame.key.get_pressed() if keys[pygame.K_a] == True: self.direction -= 1 if self.direction < -3: self.direction = 3

问题 Add on to the question here: Merge two JSON data into one with particular key values balldata.json [ { "id": "1", "color": "red", }, { "id": "2", "color": "blue", }] court.json: [ { "court_id": 2001, "ball_in_use": "1", }, { "court_id": 2005, "ball_in_use": "2", }] Now, I want to map two different json data base on it's ID. so instead of: const result = [courtdata, balldata].reduce((p, q) => p.map((c, i) => Object.assign({}, {[c.court_id] : q[i].color}))) I tried: const result = [courtdata,

问题 If I have an object like, const obj = { field: { subfield: { innerObj: { a: ' asdasd asdas . ' }, innerArr: [' s ', ' ssad . '], innerArrObj: [ { b: ' adsad ' } ], } } } I've come up with something like this, const trimFields = (data) => _.mapValues(data, (element, k) => _.isArray(element) ? element.map((value) => _.isObject(value) ? trimFields(value) : trimText(value) ) : _.isObject(element) ? trimFields(element) : trimText(element) ); But I'm wondering if there is a better / more efficient

问题 #include <stdio.h> int main(void) { char b[5]; scanf("%4s%4s", b, b); printf("%s", b); } What is the exact definition of a scalar object? Is b a scalar object in this case? 回答1: Quote from ISO/IEC 9899:2018 (C18), 6.2.5 (Types)/21: " Arithmetic types and pointer types are collectively called scalar types. Array and structure types are collectively called aggregate types.47) " 47) " Note that aggregate type does not include union type because an object with union type can only contain one

问题 I have an object, the format is such: let obj= { 'Jan 01': [ {dt: 'Jan 01', cat: 'abc', site: 'google', val1:10, val2:20, val3:30}, {dt: 'Jan 01', cat: 'abc', site: 'bing', val1:23, val2:12, val3:14}, {dt: 'Jan 01', cat: 'abc', site: 'jeeves', val1:67, val2:78, val3:12}, {dt: 'Jan 01', cat: 'pqr', site: 'google', val1:10, val2:20, val3:30}, {dt: 'Jan 01', cat: 'pqr', site: 'bing', val1:23, val2:12, val3:14}, {dt: 'Jan 01', cat: 'pqr', site: 'jeeves', val1:67, val2:78, val3:12}, {dt: 'Jan 01',

问题 I've got this question. I've been working in my project (I'm also using EMF Compare). I need to keep an unique ID for each object that I'm using, that's why I decided to use the IdentityHashCode, as far as I understand, this value is the same through the compilation. I have given the object as a parameter in the method of another class, but when I try to get the hashcode this is not the same that I can see when I print the value of the object. Something like this: System.out.println("The

问题 I am doing some basic practice for Python. Here, I am defining 3 classes. Now, I need to pass instance of first class in another class and use that in the last one. I wrote code like below: #defining first class: class MobileInventory: def __init__(self, inventory=None): if inventory == None: balance_inventory = {} elif not isinstance(inventory, dict): raise TypeError("Input inventory must be a dictionary") elif not (set(map(type, inventory)) == {str}): raise ValueError("Mobile model name
