Week1-2 的代码

from bs4 import BeautifulSoup

with open('C://personal/study/Python/Plan-for-combating-master/Plan-for-combating-master/week1/1_2/1_2answer_of_homework/index.html','r') as wb_data:

Soup = BeautifulSoup(wb_data,'lxml')

images = Soup.select("body > div > div > div.col-md-9 > div > div > div > img")

titles = Soup.select('body > div > div > div.col-md-9 > div > div > div > div.caption > h4 > a')

prices = Soup.select('body > div > div > div.col-md-9 > div > div > div > div.caption > h4.pull-right')

reviews = Soup.select("body > div > div > div.col-md-9 > div > div > div > div.ratings > p.pull-right")

stars = Soup.select('body > div > div > div.col-md-9 > div > div > div > div.ratings > p > span')

#    print(images,titles,prices,reviews,stars,sep='\n-----------------\n')

for image,title,price,review,star in zip(images,titles,prices,reviews,stars):

data = {

'title':title.get_text(),

'image':image.get('src'),

'price':price.get_text(),

'review':review.get_text(),

'star':len(star.find_all('span','glyphicon glyphicon-star'))

}

print(data)

输出如下，star 都是0，请老师点评。
