你可以试试这样

import requests

url = 'https://book.douban.com/'
response = requests.get(url)
print(response.text)

已经不用urllib了，直接用requests库不是美滋滋，你试试，而且url也不对，豆瓣是https

反爬了吧
用selenium试试吧

网站有反爬，用requests库加headers两三行代码就可以请求成功了。用urllib的话就比较麻烦，需要代码比较多，试试这个。

import urllib.request
headers = {}    # 自行添加headers
url = 'http://www.douban.com/'
re = urllib.request.Request(url=url, headers=headers)
html = urllib.request.urlopen(re)
print(html.read().decode())

得改ua，默认ua是python-urllib，豆瓣反扒。

from urllib import request

headers = {'user-agent': 'firefox'}
req = request.Request('http://www.douban.com', headers=headers)
r = request.urlopen(req)
print(r.read().decode('utf-8'))

这是不改ua的抓包。
