抓取小猪短租1000张列表页内容

代码如下

#!/usr/bin/env python
# -*- coding:utf-8 -*-

from bs4 import BeautifulSoup
import requests


def get_page_within(pages):
    for page in range(1, pages+1):
        wb = requests.get(‘http://bj.xiaozhu.com/search-duanzufang-p{}-0/‘.format(page))
        soup = BeautifulSoup(wb.text, ‘lxml‘)
        titles = soup.select(‘span.result_title‘)
        prices = soup.select(‘span.result_price > i‘)
        for title, price in zip(titles, prices):
            date = {
                ‘title‘: title.get_text(),
                ‘price‘: price.get_text()
            }
            print(date)
get_page_within(pages=1000)
针对代码解释下

from bs4 import BeautifulSoup
import requests
引入beautifulsoup和requests两个库

def get_page_within(pages):
构建def函数意思是获取pages张页面的数据

for page in range(1, pages+1):
以1为起点循环pages+1个数

wb = requests.get(‘http://bj.xiaozhu.com/search-duanzufang-p{}-0/‘.format(page))

通过.famate让括号内的数切换并且通过for循环和request库解析pages个网址的内容

soup = BeautifulSoup(wb.text, ‘lxml‘)
通过beautifulsoup库解析网页内数据

titles = soup.select(‘span.result_title‘)

prices = soup.select(‘span.result_price > i‘)
选取title和prices数据

        for title, price in zip(titles, prices):
            date = {
                ‘title‘: title.get_text(),
                ‘price‘: price.get_text()
            }
            print(date)
将获得的内容装到字典里并打印

get_page_within(pages=1000)
给def一个值运行def函数
