如何将列表项分隔为单独的变量

Question

我正在开展网络抓取项目。

我遇到了一个问题，我运行一个for循环来遍历一个列表，但它把它作为一个回来。

我的目标是将列表中的每个项目分开并将其保存为在数据框中显示它的变量，但是，我面对的是一个文本块。

我该怎么做呢

import requests
from bs4 import BeautifulSoup
import pandas

page_link = ("https://www.autotrader.co.uk/car-search?sort=price-asc&"
             "radius=1500&postcode=lu15jf&onesearchad=Used&"
             "onesearchad=Nearly%20New&onesearchad=New&make=AUDI&model=A5"
             "&price-to=8500&year-from=2008&maximum-mileage=90000"
             "&transmission=Automatic&exclude-writeoff-categories=on")

request = requests.get(page_link)
conn = request.content
soup = BeautifulSoup(conn, "html.parser")

cars = soup.find_all("h2", {"class":"listing-title title-wrap"})
cars_specs = soup.find_all('ul', {"class" :'listing-key-specs '})

carlist = []
for car, specs in zip(cars, cars_specs):
    dic = {}
    dic["Car Model"]=car.find("a", {"class": "js-click-handler listing-fpa-link"}).text
    dic["Specs"] = specs.text
    carlist.append(dic)

df = pandas.DataFrame(carlist)
df

Answer 1

我认为做什么工作

df1 = df.Specs.str.split(pat='\n', expand=True)
df1 = df1.replace('',np.nan)

df1 = df1.dropna(axis=1, how='all')
df1.columns = ['Spec_' + str(x)  for x in list(df1)]

df1
          Spec_1 Spec_2        Spec_3 Spec_4  Spec_5     Spec_6  Spec_7
