for-loop

问题 I would like to loop through several pages of data which I am accessing through an API, and concatenate the pages to the same dictionary as the loop progresses. So far I managed to loop through all the pages and could print out as the loop goes on, so when the loop is over, all the pages are printed out. But my dictionary contains only the last page! page = 5 i = 0 for i in range(0, page): url =f'http://hotell.difi.no/api/json/npd/wellbore/withcoordinates?page={i+1}' dataset_all = requests

问题 Not sure why this seemingly simple piece of code keeps crashing excel for me: Dim i as Long For i = 0.25 to 10 step 0.25 me.combobox1.addItem (i) Next i Seems pretty straight forward, I want my combobox to have a list that looks as such: 0.25 0.50 0.75 1.00 . . . 10.00 回答1: Shorter version without loop: ComboBox1.List = [text(row(1:40)/4,"0.00")] 回答2: maybe try getting rid of i from "Next i" i.e use only Next instead of Next 1 来源： https://stackoverflow.com/questions/45155642/vba-loop-to-fill

问题 I'm trying to make a simple substring search using the brute force technique but I'm getting an error which I can't see. I'm quite new to programming so please keep that in mind. The problem might be very simple. using System; using System.Collections; using System.Collections.Generic; namespace SubstringSearch { class Program { static void Main(string[] args) { Console.Write("Please enter some letters: "); string sequence = Console.ReadLine(); Console.Write("Enter the sequence you want to

问题 I was wondering how you get the sum of multiple arrays within an array of objects. My code is as follows: const employeeList = [ { "name": "Ahmed", "scores": [ "5", "1", "4", "4", "5", "1", "2", "5", "4", "1" ] }, { "name": "Jacob Deming", "scores": [ "4", "2", "5", "1", "3", "2", "2", "1", "3", "2" ] }]; var sum = 0; for(let i = 0; i < employeeList.length; i++){ var eachScore = employeeList[i].scores; const b = eachScore.map(Number); console.log(b); sum += parseInt(b);//this is the code that

问题 I'm using rsync to copy specific files from a source directory (and subdirectories) to a destination directory (and subdirectories). The mapping of the subdirectories is not identical, so I'm defining arrays of subdirectories of the destination directory that contain the source file paths. I've been unable to successfully loop over the destination arrays with access to the names of the arrays. Here's a MWE (filenames and directories must be edited, obviously). #!/bin/bash sourcedir=~/Dropbox

问题 i wrote a program to evaluate what numbers in a certain range are divisble by only certain numbers (in the range 1 to 9 ). So far the code seems to work but i tested the steps it takes through at pythontutor http://www.pythontutor.com/visualize.html#mode=edit and something odd happened. In the second loop, the code doesnt always check all values (k) for its divisibility but sometimes leaves out the last value (k) . Better to give you an example: Liste = [] for i in range (1500, 1700): if i%5

问题 I need to iterate through a range of dates. Not sure on how to take next day in for loop. I am using java.util.Date . So plusDays(1) cannot be used in the for loop for taking next date. Used date1 = new Date(date1.getTime() + (1000 * 60 * 60 * 24)) in for loop. But I don't think its a good idea to create objects by calling new each time in for loop. Please suggest a better way for taking next day in for loop. 回答1: tl;dr LocalDate.now().plusDays( 1 ) // Get tomorrow's date. Avoid legacy date

问题 I am storing the dates of Presidential speeches and each speech's respective filename in a dictionary. The speeches object looks like this: [<a href="/president/obama/speeches/speech-4427">Acceptance Speech at the Democratic National Convention (August 28, 2008)</a>, <a href="/president/obama/speeches/speech-4424">Remarks on Election Night (November 4, 2008)</a>,...] And end_link looks like: ['/president/obama/speeches/speech-4427', '/president/obama/speeches/speech-4424',...] Here's my code:

问题 Given n and k , I need to create all tuples of length k whose entries are from range(n) (0 to n-1) such that the tuple's entries are in dictionary order and there are parentheses in a particular format. Specifically, the tuple has parentheses around each pair, from inside out. For example, if n=3 and k=4 , then I would like the output to include something like (((0,0),1),2) , but not something like (((0,0),2),1) . The code below works for this specific instance. The issue is that I don't know

问题 I am trying to return a list of categories for a business, and for each category I would like to list all the items related to the category. I was returning all of my items, not by category, but I have decided I want them sorted by category. This is what I have tried (among other attempts as well) I simply am having trouble getting the items into there categories. This is my latest attempt In my models.py I have Business(models.Model): name = models.CharField(max_length=100) address = models
