python怎么解压压缩的字符串数据

范例1: gzip

import StringIO
import gzip

compresseddata = gzip方式压缩的字符串(html)
compressedstream = StringIO.StringIO(compresseddata)
gzipper = gzip.GzipFile(fileobj=compressedstream)
data = gzipper.read() # data就是解压后的数据

一个简单的例子

 import urllib2
 from StringIO import StringIO
 import gzip

 def loadData(url):
     request = urllib2.Request(url)
     request.add_header('Accept-encoding', 'gzip')
     response = urllib2.urlopen(request)
     if response.info().get('Content-Encoding') == 'gzip':
         print 'gzip enabled'
         buf = StringIO(response.read())
         f = gzip.GzipFile(fileobj=buf)
         data = f.read()
     else:
         data = response.read()
     return data
