问题 Due to my current understanding of Python's syntax, I have run into an issue where I need to set a variable to a value but without using any operators. I have to use functions. Consider this senario class Senario: x: str = '' y: str = '' set_global_variable(self, set_variable, val: str) # some verification code and modifications set_variable(val) set_x(self, val: str) self.set_global_variable(setX, val) set_x(self, val: str) self.set_global_variable(lambda new_x: self.x = new_x, val) The

问题 I have the following class, UNetwork . It is there for reference. The actual question is related to the second class, Model . class UNetwork(object): nodes = dict() def _init_(self, nodes): self.nodes = nodes Now, the class ( Model ) has the following attributes: network — an instance of class UNetwork taken at instantiation; susceptible_nodes — a list of ids for nodes that are not yet infected; initially includes all nodes from network; infected_nodes — a list of ids for nodes that are

问题 Here is the code snippet that I am working on and my goal is to find the largest value from the list using predefined java methods. import java.util.*; public class Test { public static void main(String[] args) { Scanner s = new Scanner(System.in); System.out.println("Enter a list of integers: "); int array[] = new int[10]; for (int i = 0; i < array.length; i++) { array[i] = s.nextInt(); } for (int j = 0; j < array.length; j++) { if (j < array.length) { int maximum = Math.max(array[j], array

问题 I know I can find a list of mutator methods on MDN, still, in practice I always forget if methods like push() or reverse() mutates the original array or creates a new one. Is there a logic to why certain methods are mutators and some are non-mutators, so I can easily remember? 回答1: Maybe a helpful way to remember them is to identify the mutating methods and group them; there's only a small amount. Add/remove from array: Array.prototype.fill() - overwrite elements anywhere Array.prototype.pop(

问题 I have an object and I want to dynamically call a method on it. Having typechecking would be nice but that maybe impossible. But I can't even get it to compile at all currently: const key: string = 'someMethod' const func = this[key] func(msgIn) gives me this error... Element implicitly has an 'any' type because expression of type 'any' can't be used to index type 'TixBot'. I tried some other type options without success. const key: any = cmd.func const func: any = this[key] Apart from @ts

问题 I have created my menu with do~while(true); but every time the user insert a number, instead of running the program it shows the the menu again! what do you think? // my main method public static void main(String[] args) { DataReader reader = new DataReader(); // The reader is used to read data from a file // Load data from the file if(reader.loadData(args[0])) { // The filename is entered using a command-line argument vehicles= reader.getVehicleData(); // Store the arrays of Vehicle //
