使用方法：
from bs4 import BeautifulSoup
拿到html后使用find_all()拿到文本数据，下图可见，数据标签为：
content_text = soup.find_all('span', class_='show_dp f_r')
因为优点，缺点，综述的classname一样，所以写了个小分类：
for index,x in enumerate(content_text):if index % 3 == 0:with open("car_post.txt", "a", encoding='utf-8') as f:f.write(x.text+"\n")elif index % 3 == 1:with open("car_nev.txt", "a", encoding='utf-8') as f:f.write(x.text+"\n")else:with open("car_text.txt", "a", encoding='utf-8') as f:f.write(x.text+"\n")结果预览
