I wrote a great upload callback for boto S3 stuff

archive_logs

import itertools, sys

SPINNER = itertools.cycle(['-', '/', '|', '\\'])

def upload_callback(bytes_sent, bytes_total):
    cols = 67
    if bytes_total > 0:
        percent = bytes_sent / float(bytes_total)
    else:
        percent = 0
    numbar = int(cols * percent)
    sys.stdout.write("\n\x1b[1A\x1b[2K" + "[%-67s %s % 3d%%]" % \
                         ('=' * numbar, SPINNER.next(), int(percent * 100)))


# you can test it like so too:
import time
i = 1
while i < 100:
   upload_callback(i, 100)
   i += 1
   time.sleep(0.05)
upload_callback(100, 100)
print
