Python爬取附近餐馆信息代码示例

本代码主要实现抓取大众点评网中关村附近的餐馆有哪些,具体如下:

import urllib.request 
import re 

def fetchFood(url): 
  # 模拟使用浏览器浏览大众点评的方式浏览大众点评 
  headers = {'User-Agent', 
        'Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36'} 
  opener = urllib.request.build_opener() 
  opener.addheaders = [headers] 
  data = opener.open(url).read() 
  data = data.decode('utf') 
   print('================================抓取的页面数据=======================================') 
  print(data)   # 打印抓取的页面 
   print('================================获取的餐馆信息====================================') 
  foodNameSet = set(re.compile(r'<img title="(.*?)"', re.DOTALL).findall(data)) 
  number = 0 
  for i in foodNameSet: 
    number = number + 1 
    print("第%d个餐馆: %s" % (number, i)) 
foodUrl = "http://www.dianping.com/search/category/2/10/r1488" 
fetchFood(foodUrl)

输出结果:
