TypeError: css() takes exactly 2 arguments (3 given)

Receiving the following error, TypeError: css() takes exactly 2 arguments (3 given), when trying to run the following web scraping program. I need the program to scrape these card names from the following website, http://www.starcitygames.com/catalog/category/Duel%20Decks%20Venser%20vs%20Koth and the problem is in order to scrape all the content I need I have to have two variables in the loop. But I do not know if I even set the loop up right for it to work simultaneously for it to look for both strings in the HTML code.

SplashSpider.py

import csv
from scrapy.spiders import Spider
from scrapy_splash import SplashRequest
from ..items import GameItem

# process the csv file so the url + ip address + useragent pairs are the same as defined in the file # returns a list of dictionaries, example:

Solution

You need this CSS expression (similar to starts-with()):

for game in response.css("tr[class^=deckdbbody]"):
    # Card Name
    item["card_name"] = game.css("a.card_popup::text").extract_first()
