python爬取豆瓣读书top250并保存xls（含源码）

又是霍霍豆瓣的一天O(∩_∩)O哈哈~。
目标网站：http://book.douban.com/top250/
全军出击！！！
首先，按下F12

可以点击左上角小按钮快速查看xpath哦

ok，开始爬虫！
首先导入库

import re
import xlwt
import requests
from bs4 import BeautifulSoup

因为xlwt和bs4不是python自带的库，所以我们要自行去cmd: pip install xlwt , pip install bs4
第二步，初始化各种信息

def getHtml(url):  headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0'}  page = requests.get(url,headers = headers)html =page.textreturn html

然后，写入xls的几行代码

    sheet = Workbook.add_sheet('豆瓣图书Top250')sheet.write(2,2,'书名')sheet.write(2,3,'作者')sheet.write(2,4,'译者')sheet.write(2,5,'出版单位')sheet.write(2,6,'出版时间')sheet.write(2,7,'定价')sheet.write(2,8,'豆瓣评分')sheet.write(2,9,'评价人数')sheet.write(2,10,'短评')i = 3j = 3k = 3m = 3

i,j,k,m是每次写入时位置的变量。
第三步，筛选与写入，我就不详细讲了，差不多就是从源码中的信息中使用xpath筛选出要的信息。

for page in range(0,250,25):url = 'https://book.douban.com/top250?start={0}'.format(page)html = getHtml(url)Soup = BeautifulSoup(html,'html.parser')names = Soup.find_all('div',class_ = 'pl2')for name in names:book = name.find('a')book = book.text.strip()book = book.replace(' ','')sheet.write(i,2,book)i += 1Infos = Soup.find_all('p',class_ = 'pl')for Info in Infos:r = 1authorinfo =  Info.textauthors = authorinfo.split('/')if len(authors) < 4:sheet.write(j,5,authors[0])sheet.write(j,6,authors[1])sheet.write(j,7,authors[2])j += 1continuesheet.write(j,3,authors[0])if authorinfo.count('/') == 4:sheet.write(j,4,authors[r])r += 1sheet.write(j,5,authors[r])sheet.write(j,6,authors[r+1])sheet.write(j,7,authors[r+2])j += 1rating_nums = Soup.find_all('div',class_ = 'star clearfix')for rating in rating_nums:star = rating.find_all('span')sheet.write(k,8,star[1].text)reg = r'\d+'vote = re.findall(reg,star[2].text)sheet.write(k,9,vote)k += 1quotes = Soup.find_all('p',class_ = 'quote')for quote in quotes:sheet.write(m,10,quote.text)m += 1

最后，保存并关闭xls

Workbook.save('豆瓣图书Top250.xls')

源码贴上来：

#coding=utf-8

import xlwt
import requests
