    no inputstream?

    hey folks,

    coming from java, new to python. i'm trying to port a java app to
    python that writes an inputstream to a buffer, then parses the buffer
    (specifically, i'm getting ID3 tags from mp3s online). i understand
    that this java approach to the task may not apply to python, but i'm
    having trouble finding a working approach in python.

    i currently have locations of the mp3s in question as strings, which
    works for parsing local files, but gives me a "No such file or
    directory" error when it tries to process URLs. it seems terribly
    inefficient to download each mp3 just to get at that small tag data,
    and i assume there's a way to do this with file() or open() or
    something, i just can't get it to work.

    anyone know how i can fix this? thanks in advance for any help!

    best,
    max

      You can use `urllib2.urlope n()` to open URLs as files. But if you deal
      with ID3 V1 tags you'll have to download the file anyway because those are
      in the last 128 bytes of an MP3 file.

          Just don't import time. What would you do with an autolocking timer,
          such as time.sleep( ) on a thread? I am tongue tied in the presence
          of a lady.

              thanks guys. i guess i just figured there'd be a way to get at those
              id3 bytes at the end without downloading the whole file. if java can
              do this, seems like i should just stick with that implementation, no?
