スクレイピング

imgタグのみを抽出する.

# encoding : utf-8
# for python3
import urllib.request
import os.path
import pyquery as pq
import requests
from bs4 import BeautifulSoup
import urllib.request
from urllib.request import Request, urlopen

#def download(url,folderName):
def scraping():
    url = 'http://umashika5555.hatenablog.com/'#まずはurlをぶち込む
    req = Request(url)
    response = urlopen(req)#開け！url
    html = response.read()#htmlを読み込んでぶち込む
    soup = BeautifulSoup(html, "lxml")#ここでBeautifulsoupの出番だぁっ
    #contents = soup.find_all(id = 'contents') #今回抜き出したいタグ
    contents = soup.find_all("img") #今回抜き出したいタグ
    for i,content in enumerate(contents): 
        print(i,end="")
        print('-'*50)
        print(content)
        

			
if __name__ == '__main__':
	scraping() 

こんな感じの結果が得られる.
