A python script to do asynchronous upload to google storage using boto and eventlet libraries

eventlet_gs_uploader.py

# this program uploads to google storage using boto and eventlet all the jpg files of a selected folder

import eventlet
bcon = eventlet.import_patched("boto.gs.connection")
import glob
FOLDER = "/Users/myself/Documents/" # replace this with your chosen folder
BUCKET_NAME = "whateveryourbucketname"  # replace this with your bucket name

def upload(myfile):
        c = bcon.GSConnection()
        bucket = c.get_bucket(BUCKET_NAME)
        key = bucket.new_key(myfile)
        with open("{0}{1}".format(FOLDER , myfile), "rb") as f:
                print "begin upload of ", myfile
                key.set_contents_from_file(f, policy="private")
                print "uploaded", myfile

        return myfile

if __name__ == "__main__":
        pool = eventlet.GreenPool(200)
        for fname in pool.imap(upload, [x.split("/")[-1] for x in glob.glob("{0}*jpg".format(FOLDER)) ]):
                print "file ", fname , " at google storage"

This python script works with python 2.6. I think there are some issues with using eventlet in python 2.7. I tried with python 2.7rc1 but failed.
