问题 I'm writing my first real scraper and although in general it's been going well, I've hit a wall using Selenium. I can't get it to go to the next page. Below is the head of my code. The output below this is just printing out data in terminal for now and that's all working fine. It just stops scraping at the end of page 1 and shows me my terminal prompt. It never starts on page 2. I would be so grateful if anyone could make a suggestion. I've tried selecting the button at the bottom of the page

问题 I am currently trying to scrape a dynamic website which uses javascript to provide information after hovering over images. I am trying to obtain the data inside of the text containers brought up by hovering over these images, but am having difficulty doing so because when I define all of the elements, then attempt to create a loop which hovers over all of them, I only receive the text data from the first element I defined, over and over as many elements as there are (10 on this page.) Here is
