Scrapy init returns a None - web-scraping

Question

I have a scrapy scrawling script.
class QuotesSpider(scrapy.Spider):
name = 'quotes'
def __init__(self, *args, **kwargs):
super(QuotesSpider, self).__init__(*args, **kwargs)
self.cat = [kwargs.get('cat')]
print(self.cat)
def start_requests(self):
#print(self.params)
urls = ['https://google.com/html/?q=a%v%c']
for url in urls:
yield scrapy.Request(url=url, callback=self.parse)
On command line:
scrapy crawl quotes -a cat="avc"
When I run the command:
It prints "None"
How can I access the value "avc" passed through the command line in the program

Answer 1

There are things missing in your code. Check out the below sample code
class QuotesSpider(scrapy.Spider):
name = 'quotes'
def __init__(self, *args, **kwargs):
super(QuotesSpider, self).__init__(*args, **kwargs)
self.cat = kwargs.get('cat')
print(self.cat)
def start_requests(self):
# print(self.params)
urls = [f"https://www.google.com/search?q={self.cat}"]
# urls = ['https://google.com/html/?q=a%v%c']
for url in urls:
yield scrapy.Request(url=url, callback=self.parse)
def parse(self, response):
print(response, "Response <---")
The requested google URL was wrong, I have changed it with the new one.
<200 https://www.google.com/search?q=avc> Response <---
