When I was new to Python, I wanted to customize the Item and reference it when I was learning crawlers. The custom Item is shown below

import scrapy

​​​​​​​
class MyItem(scrapy.Item):
    title = scrapy.Field()
    pass

In the crawler file, the code is as follows:

# -*- coding: utf-8 -*-

import scrapy
from tutorial.items.MyItem import MyItem


class MySpider(scrapy.Spider):
    name = 'myitem.demo'
    allowed_domains = ['toscrape.com']

    def start_requests(self):
        yield scrapy.Request('http://toscrape.com/tag/humor/', self.parse)

    def parse(self, response):
        for h1 in response.xpath('//h1').getall():
            yield MyItem(title=h1).print_item()

        for href in response.xpath('//a/@href').getall():
            yield scrapy.Request(response.urljoin(href), self.parse)

Here, Tutorial.item.myItem needs to write the class file name
