如何使用python通过HTTP从远程zip存档读取所选文件?

import urllib2, cStringIO, zipfile

try:
    remotezip = urllib2.urlopen(url)
    zipinmemory = cStringIO.StringIO(remotezip.read())
    zip = zipfile.ZipFile(zipinmemory)
    for fn in zip.namelist():
        if fn.endswith(".ranks"):
            ranks_data = zip.read(fn)
            for line in ranks_data.split("\n"):
                # do something with each line
except urllib2.HTTPError:
    # handle exception

import urllib.request, io, zipfile

try:
    remotezip = urllib.request.urlopen(url)
    zipinmemory = io.BytesIO(remotezip.read())
    zip = zipfile.ZipFile(zipinmemory)
    for fn in zip.namelist():
        if fn.endswith(".ranks"):
            ranks_data = zip.read(fn)
            for line in ranks_data.split("\n"):
                # do something with each line
except urllib.request.HTTPError:
    # handle exception
