爬取豆瓣电影排名代码

urllib.request爬取电影排名，复制以下代码可以直接执行：

-- coding:utf-8 --

import urllib
import urllib.request
import time
import json
import re

url = “https://movie.douban.com/j/chart/top_list?type=11&interval_id=100%3A90&action”

headers = {“User-Agent” : “Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36”}

formdata = {
“start”:“0”,
“limit”:“20”
}

data = urllib.parse.urlencode(formdata).encode(“utf-8”)

request = urllib.request.Request(url, data = data, headers = headers)

dd=urllib.request.urlopen(request).read()

s=dd.decode(‘utf-8’) #bytes转普通字符串

#print(s)

data2=json.loads(s) #将json字符串转换成python对象，在这里转换成了list

print(data2[0][“title”])

#“rating”:[“9.6”,“50”]
#“title”:“肖申克的救赎”,

pattern1=re.compile(r’“rating”:["(.?)","\d+"]’,re.I) #获取电影得分
pattern2=re.compile(r’“title”:"(.?)"’,re.I) #获取电影名字

data1=pattern1.findall(s)
data2=pattern2.findall(s)

for x in range(len(data1)):
print(“排名：”+str(x+1)+“电影名：”,data2[x],“豆瓣得分：”+data1[x])
