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()

希望本文所述对大家的python程序设计有所帮助。
