python爬虫爬取大众点评并导入redis

直接上代码，导入redis的中文编码没有解决，日后解决了会第一时间上代码！新手上路，多多包涵！

# -*- coding: utf-8 -*-
import re
import requests
from time import sleep, ctime
from urllib.request import urlopen
from urllib.request import Request
from lxml import etree
import redis
import MySQLdb


r = redis.Redis(host='192.168.60.112', port=6379,db=0)#host自己的ip地址

# 添加模拟浏览器协议头
headers = {'User-Agent': 'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6'}
for page in range(1，3):#爬取第1页到第3页。
#大众点评链接，用了字符串拼串
    url = "http://www.dianping.com/search/category/2/10/g112p%i"%(page)+"?a#字符串拼接
    # print(url)
    req_timeout = 5#延时
    req = Request(url=url, headers=headers)
    f = urlopen(req, None, req_timeout)
    s = f.read()
    s = s.decode('utf-8')
    ss = str(s)
    # lxml提取
    selector = etree.HTML(ss)
#爬的内容
    links = selector.xpath(
        '//div[@class="txt"]/div[@class="tit"]/a/@href|//div[@class="txt"]/div[@class="tit"]/a/h4/text()')

    for link in links:
        print(link)
#写入redis，用的list类型（栈结构）
        r.lpush('mylist',link)
