loops

问题 How can I have more than one loop running ate the same time using the same function but using different parameters like: @tasks.loop(seconds = 10) async def loop(name): Print(name) loop.start("Jon") loop.start("Joseph") Is this how u pass parameters to loops? 回答1: You need to create a new Loop object for each loop. You can do this by using regular function calling repeatedly instead of the decorator: async def loop(name): print(name) names = ["Jon", "Joseph"] loops = {name: tasks.loop(seconds

问题 I'm a complete beginner in React and I was pretty happy with my first app since I, maybe, have a memory leak ? My app is very laggy after entering value in the input, after click on the add button, at bottom right, and I suspect that I don't use 'useState' like I should ? I dunno, I've been searching for hours :( ... Here's the app : https://n3g.gitlab.io/react-conso-energie/ Here's the code : In the App.js (parent) : import React, { useState } from 'react' import firebase from './firebase'

问题 I am so called newbie in Python. I have difficulties with lists. I have a loop which take some info from textfile and goes through function. If textfiles lenght is 10 rows then output will be 10 separate lists, like that: [0.45] [0.87] ... and so on, for n+1 times(it depends how long textfile is). How can I put them into single list, like [0.45, 0.87, ...]? I experimented with different loops but nothing :( I am previously thankfull :) .. and sry about my bad english Code: from pyfann import

问题 UPDATE - Wondering if it has to do with this line in the PHP function - $cid[] =''; I am getting the dreaded undefined index but even after reading SO answers about it, I am uncertain why the index isn't existing in my instance. I get that the index is missing which is why I see the error, I am not sure why the index is missing however. Is it the initial construction of the string that is causing the issue? Is it the way I am retrieving the $_POST['Cid'] ? When I var-dump I get the expected

问题 I am trying to create a moodle-STACK question with an interactive element via jsxgraph . Within the [[jsxgraph]] ... [[/jsxgraph]] tags, I am plotting a curve with two databases, each with 6 elements. Since I would like students to add error bars for both scales, I added a loop within the jsxgraph-element : var plot = function() { var j, xr0, yr0, xr1, yr1, xr2, yr2, err1, err2; board.suspendUpdate(); for (j=0; j<6;j++) { const v1 = Number(input1.Value()); const v2 = Number(input2.Value());
