Bytes/File Size Format Function

[samuraisam]

Quick file size formatting for all those seekers out there...

import math

def filesizeformat(bytes, precision=2):
    """Returns a humanized string for a given amount of bytes"""
    bytes = int(bytes)
    if bytes is 0:
        return '0bytes'
    log = math.floor(math.log(bytes, 1024))
    return "%.*f%s" % (
        precision,
        bytes / math.pow(1024, log),
        ['bytes', 'kb', 'mb', 'gb', 'tb','pb', 'eb', 'zb', 'yb']
[int(log)]
    )
