Python libraries to calculate human readable filesize from bytes?

44

This isn't really hard to implement yourself:

suffixes = ['B', 'KB', 'MB', 'GB', 'TB', 'PB']
def humansize(nbytes):
    i = 0
    while nbytes >= 1024 and i < len(suffixes)-1:
        nbytes /= 1024.
        i += 1
    f = ('%.2f' % nbytes).rstrip('0').rstrip('.')
    return '%s %s' % (f, suffixes[i])

Examples:

>>> humansize(131)
'131 B'
>>> humansize(1049)
'1.02 KB'
>>> humansize(58812)
'57.43 KB'
>>> humansize(68819826)
'65.63 MB'
>>> humansize(39756861649)
'37.03 GB'
>>> humansize(18754875155724)
'17.06 TB'
