Practical first Python code reference
#!/usr/bin/env python
import urllib
import re
x=0
def getHtml(url):
page = urllib.urlopen(url)
html = page.read()
return html
def getImg(html):
global x
reg = 'alt=".+?" src="(.+?\.jpg)"'
imgre = re.compile(reg)
imglist = re.findall(imgre,html)
for imgurl in imglist:
urllib.urlretrieve(re.sub(r',\d+,\d+',',800,450',imgurl),"img/%s.jpg" % x)
print "\n"+re.sub(r',\d+,\d+',',800,450',imgurl)+"========"+"img/%s.jpg" % x
x+=1
print 'Starting...'
pages = range(1,9)
for p in pages:
html = getHtml('http://m.lovebizhi.com/category/7655/%d/' % p)
print "\n-------------------------page:%d-------------------------------" % p
getImg(html)
print "\nDone!"
Above is the article to share all the code, I Python rookie, the first work, I hope to help you.
