我是python编程和网页抓取的新手。我的目标代码是抓取网站中书籍的标题，价格和网址。然而，我无法在我的终端中获得想要的消息，这是“item_scraped_count”，通常已包含在教程终端中，与我的相反。
这是我的代码块

import scrapy

class BookspiderSpider(scrapy.Spider):
    name = "bookspider"
    allowed_domains = ["books.toscrape.com"]
    start_urls = ["https://books.toscrape.com/"]

    def parse(self, response):
        books = response.css('article.product_prod')

        for book in books:
            yield{
                'title' : book.css("h3 a::text").get(),
                'price' : book.css(".product_price .product_color::text").get(),
                'url' : book.css("h3 a").attrib['href']
            }

        next_page = response.css("li.next a::attr(href)").get()

        if next_page is not None:
            if 'catalogue/' in next_page:
                next_page_url = 'https://books.toscrape.com/' + next_page
            else:
                next_page_url = 'https://books.toscrape.com/catalogue/' + next_page
            yield response.follow(next_page_url, callback=self.parse)

字符串
这是终端中的结果：

我想提前感谢你帮我解决这个问题
我试图在终端中获取“item_scraped_count”，但它不显示
