python获得 豆瓣网正在上映前十五名电影评分

2018.12.23更新：假如你使用的是anaconda安装的lxml库，可能需要更改 以下代码 ，直接是python3.7+pycharm的话我这边我的代码是没有问题能运行的。 

from lxml import html
#导入包不在是import etree
...
...

htmlelement = html.etree.HTML(text)
#这边变量的名字得改一下，HTML解析的方法也得改

#不保证有用，因为博主没试过。也是看文档才发现这个改了

 

import requests                    #需要安装request库和lxml库
from lxml import etree

headers = {
    'User_Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebK\
    it/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36',
    'Referer':'https://www.baidu.com/s?ie=UTF-8&wd=douban'
}
url = "https://movie.douban.com/cinema/nowplaying/nanchang/"
#修改豆瓣网的正在上映url，最后的地区拼音不一样


res = requests.get(url)
text = res.text

html = etree.HTML(text)
ul = html.xpath("//ul[@class='lists']")[0]
lis = ul.xpath("./li")
for li in lis:
    title = li.xpath("@data-title")[0]
    score = li.xpath("@data-score")[0]
    if score == "0":
        score = "暂无评分"
    print("电影名:%s"%title)
    print("电影评分:%s"%score)
    print("")

改进版：

import requests
from lxml import etree

headers = {
    'User_Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebK\
    it/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36',
    'Referer':'https://www.baidu.com/s?ie=UTF-8&wd=douban'
}
urlori = "https://movie.douban.com/cinema/nowplaying/"
location = input("输入你所在市名拼音")
url = urlori+location
print(url)
res = requests.get(url)
text = res.text

html = etree.HTML(text)
ul = html.xpath("//ul[@class='lists']")[0]
lis = ul.xpath("./li")
for li in lis:
    title = li.xpath("@data-title")[0]
    score = li.xpath("@data-score")[0]
    if score == "0":
        score = "暂无评分"
    print("电影名:%s"%title)
    print("电影评分:%s"%score)
    print("")
