Answer by Dima First for Scrapy runs all spiders at once. I want to only run one spider at a time. Scrapy crawl

You can run scrapy from your script (https://scrapy.readthedocs.io/en/latest/topics/practices.html#run-from-script), for example:

import scrapy
from scrapy.crawler import CrawlerProcess

class YourSpider(scrapy.Spider):
    # Your spider definition


process = CrawlerProcess()
process.crawl(YourSpider)
process.start()
