Stop Scrapy from logging spider output to Visual Studio Code terminal - visual-studio-code

Question

Whenever I run my spider scrapy crawl test -O test.json in my Visual Studio Code terminal I get output like this:
2023-01-31 14:31:45 [scrapy.core.scraper] DEBUG: Scraped from <200 https://www.example.com/product/1

I want to log all this, including the print('hi') lines in my Spider but I DON'T want the spider output logged, in this case {'price': 100, 'newprice': 90 }.
Inspecting the above I think I need to disable only the downloader/response_bytes.
I've been reading this https://docs.scrapy.org/en/latest/topics/logging.html, but I'm not sure where or how to configure my exact use case. I have hundreds of spiders and I don't want to have to add a configuration in each, but rather apply the loggin config to all spiders. Do I need to add a separate config file or add to an existing like scrapy.cfg?
UPDATE 1
So here's my folder structure where I created settings.py:
Scrapy\
tt_spiders\
myspiders\
spider1.py
spider2.py
settings.py
middlewares.py
pipelines.py
settings.py
scrapy.cfg
settings.py
settings.py
if __name__ == "__main__":
disable_list = ['scrapy.core.engine', 'scrapy.core.scraper', 'scrapy.spiders']
for element in disable_list:
logger = logging.getLogger(element)
logger.disabled = True
spider = 'example_spider'
settings = get_project_settings()
settings['USER_AGENT'] = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36'
process = CrawlerProcess(settings)
process.crawl(spider)
process.start()
This throws 3 errors, which makes sense as I have not defined these:
"logging" is not defined
"get_project_settings" is not defined
"CrawlerProcess" is not defined
But more importantly, what I don't understand, this code contains spider = 'example_spider',
where I want this logic to apply to ALL spiders.
So I reduced it to:
if __name__ == "__main__":
disable_list = ['scrapy.core.scraper']
But still the output is logged. What am I missing?

Let's assume that we have this spider:
spider.py:
import scrapy
class ExampleSpider(scrapy.Spider):
name = 'example_spider'
allowed_domains = ['scrapingclub.com']
start_urls = ['https://scrapingclub.com/exercise/detail_basic/']
def parse(self, response):
item = dict()
item['title'] = response.xpath('//h3/text()').get()
item['price'] = response.xpath('//div[#class="card-body"]/h4/text()').get()
yield item
And its output is:
...
[scrapy.middleware] INFO: Enabled item pipelines:
[]
[scrapy.core.engine] INFO: Spider opened
[scrapy.extensions.logstats] INFO: Crawled 0 pages (at 0 pages/min), scraped 0 items (at 0 items/min)
[scrapy.extensions.telnet] INFO: Telnet console listening on 127.0.0.1:6023
[scrapy.core.engine] DEBUG: Crawled (200) <GET https://scrapingclub.com/exercise/detail_basic/> (referer: None)
[scrapy.core.scraper] DEBUG: Scraped from <200 https://scrapingclub.com/exercise/detail_basic/>
{'title': 'Long-sleeved Jersey Top', 'price': '$12.99'}
[scrapy.core.engine] INFO: Closing spider (finished)
[scrapy.statscollectors] INFO: Dumping Scrapy stats:
{'downloader/request_bytes': 329,
'downloader/request_count': 1,
...
If you want to disable logging for specific line then just copy the text inside the square brackets and disable its logger.
e.g.: [scrapy.core.scraper] DEBUG: Scraped from <200 https://scrapingclub.com/exercise/detail_basic/>.
main.py:
if __name__ == "__main__":
disable_list = ['scrapy.core.engine', 'scrapy.core.scraper', 'scrapy.spiders']
for element in disable_list:
logger = logging.getLogger(element)
logger.disabled = True
spider = 'example_spider'
settings = get_project_settings()
settings['USER_AGENT'] = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36'
process = CrawlerProcess(settings)
process.crawl(spider)
process.start()
If you want to disable some of the extensions you can set them to None in settings.py:
EXTENSIONS = {
'scrapy.extensions.telnet': None,
'scrapy.extensions.logstats.LogStats': None,
'scrapy.extensions.corestats.CoreStats': None
}
Update 1:
Add just this to settings.py:
import logging
disable_list = ['scrapy.core.engine', 'scrapy.core.scraper', 'scrapy.spiders']
for element in disable_list:
logger = logging.getLogger(element)
logger.disabled = True
