使用Scrapy项一次赋值多个变量

import scrapy

class MySpider(scrapy.Spider):
    name = 'example'
    start_urls = ['http://www.example.com']

    def parse(self, response):
        # 使用XPath选择器提取多个变量的值
        title = response.xpath('//title/text()').get()
        description = response.xpath('//meta[@name="description"]/@content').get()

        # 使用CSS选择器提取多个变量的值
        author = response.css('div.author::text').get()
        date = response.css('div.date::text').get()

        # 打印提取到的变量值
        print('Title:', title)
        print('Description:', description)
        print('Author:', author)
        print('Date:', date)
