问题 I have a data set that includes a range of dates and need to fill in the missing dates in new rows. df1 is an example of the data I am working with and df2 is an example of what I've managed to achieve (where I'm stuck). df3 is where I would like to end up! df1 ID Date DateStart DateEnd 1 2/11/2021 2/11/2021 2/17/2021 1 2/19/2021 2/19/2021 2/21/2021 2 1/15/2021 1/15/2021 1/20/2021 2 1/22/2021 1/22/2021 1/23/2021 This is where I am with this.

问题 The idea was to put a tooltip with value related to slider. I thought initially to accomplish that task by using css grid . CSS provides you with grid of any size, 10 or 1000 cols, doesn't matter. By utilizing grid functionality, we can align out tooltip as we wish. What we really get is: Thumb position is sort of unpredictable. It seems that it is being offset, and the direction of that offset is dependent on whether input value is in the left or right part of slider. Note: default thumb

问题 How do I set an image as a thumb slider on range input type with css? It doesn't work in Internet Explorer. Chrome and Firefox is ok, but on IE my image is hidden or something? I use ::-ms-thumb , and try to set image as background. how can I fix it with CSS? input[type="range"]::-webkit-slider-thumb { -webkit-appearance: none; background-image: url('../images/slider.png'); opacity: 1; width: 40px; height: 19px; position: relative; top: 0px; z-index: 99; } ::-moz-range-thumb{ background-image

问题 I have got a problem in assigning new value by list. I want to change 12 items values in s numpy by numpy array's index ,and i hope every index i choose is different. so i made a list random.sample(range(0,len(s),12) to select 12 different index.And through this index change some of values in numpy array s() However, I'm getting the error: SyntaxError: can't assign to function call import numpy as np import random N = 20 s = np.zeros([N]) alist = random.sample(range(0,20),12) alist for i in

问题 I have a C program where a CSV file containing 8 x,y coordinates are inserted into a linked list. Each of the 8 coordinates belongs in a 2x2 grid. There are 4 grids as seen in the picture below: First I want my program to determine which coordinate belongs in which grid. Once I've determined that, for each grid, I want to sum all of the x-coordinates and y-coordinates. Then for each grid 1-4, I want to then print the total sum of the x coord and y coord. #include <stdio.h> #include <stdlib.h>

问题 I am trying to get the range of numbers using recursion. Can someone explain to me why it isn't working? function range(x,y){ var results = []; if(x === y){ return results; } return results.push(range(x + 1,y)); } range(1,5); 回答1: Try this: function rangeOfNumbers(startNum, endNum) { if (startNum - endNum === 0) { return [startNum]; } else { const numbers = rangeOfNumbers(startNum + 1, endNum); numbers.unshift(startNum); return numbers; } }; 回答2: The beauty of recursion is that you don't need
