scraping data from web-CodePudding

I am trying to scrap prices, miles and models of different cars from truecar.com. I think, I find appropriate tags from the website but my code doesn't give me the suitable data. my code give me empty data and I do not find the problem. May you please help me? I receive unexpected indent when defining price, miles and model.

import requests
from bs4 import BeautifulSoup
import mysql.connector
url='https://www.truecar.com/used-cars-for-sale/listings/'
r=requests.get(url)
soup=BeautifulSoup(r.text,'html.parser')

data = []
for card in soup.select('[]'):
    price = card.select_one('[]').text

    miles = card.select_one('div[]').text

    models=card.select_one('div[]').text

    data.append({'price':price,'miles':miles,'models':models})

print(data)

You can use the following selectors to fetch the data.

import requests
from bs4 import BeautifulSoup

url='https://www.truecar.com/used-cars-for-sale/listings/'
r=requests.get(url)

soup=BeautifulSoup(r.text,'html.parser')

cards = soup.select('div.linkable.card.card-shadow.vehicle-card._1qd1muk')

data = []
for card in cards:
    vehicleCardYearMakeModel = card.find("div", {"data-test" : "vehicleCardYearMakeModel"}).text.replace('Sponsored', '')
    vehicleMileage = card.find("div", {"data-test" : "vehicleMileage"}).text
    vehiclePrice = card.find("div", {"data-test" : "vehicleCardPricingBlockPrice"}).text
    data.append({'price':vehiclePrice,'miles':vehicleMileage,'models':vehicleCardYearMakeModel})

which gives you the expected output

Issue cause you wont get any result is, that there is a whitespace in one of you class names in the first selection. So there is nothing to iterate and your for-loop wont start. Fix this and you will get your results from the rest of your code:

soup.select('[]

instead of:

soup.select('[]
