<p>I need to read selected files, matching on the file name, from a remote zip archive using Python. I don't want to save the full zip to a temporary file (it's not that large, so I can handle everything in memory).</p>

<p>I've already written the code and it works, and I'm answering this myself so I can search for it later. But since evidence suggests that I'm one of the dumber participants on Stackoverflow, I'm sure there's room for improvement.</p>

Here's how I did it (grabbing all files ending in ".ranks"):
```
```
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
```
```
