Python实现豆瓣图片下载的方法


            本文实例讲述了Python实现豆瓣图片下载的方法。分享给大家供大家参考。具体分析如下：

1 用 tk 封装一下

2 用户可以自己输入图片url





download_douban_album

# -*-coding:UTF-8 -*-

import re

import urllib

def count_percent(a, b, c):

  per = 100.0 * a * b / c

  if per > 100:

    per = 100

  print '%.2f%%' % per

def get_url():

  n = [x*18 for x in range(0, 87)]

  url_list = []

  for i in n:

    url = 'http://www.douban.com/photos/album/73174384/?start=%s' % i

    url_list.append(url)

  return url_list

def get_img_url():

  img_url = []

  url = get_url()

  for u in url:

    a = urllib.urlopen(u)

    for line in a.readlines():

      if 'thumb' in line:

        img_url.append(line.strip()[10:-4].replace('thumb', 'photo'))

  return img_url

def download_img():

  download_url = get_img_url()

  for u in download_url:

    urllib.urlretrieve(u, 'd:\\New\\%s' % u.split('/')[-1])

if __name__ == '__main__':

  """a = get_img_url()

  f = open('d:\\thumb.txt', 'w')

  for i in a:

    #j = i.replace('thumb', 'photo')

    f.write(i+'\n')

  f.close()"""

  download_img()
