Print human readable file size.

Often you have to print a file or a directory size. Here is a small recipe to print a file, or a directory size easily readable by humans. 

def sizeof_fmt(num):
    for x in ['bytes','KB','MB','GB','TB']:
        if num < 1024.0:
            return "%3.1f%s" % (num, x)
        num /= 1024.0

def sizeof_fmt(num):
for x in ['bytes','KB','MB','GB','TB']:
if num < 1024.0:
return "%3.1f%s" % (num, x)
num /= 1024.0

Example:
>>> sizeof_fmt(168963795964)
'157.4GB'

>>> sizeof_fmt(168963795964)
'157.4GB'

Don't you want to use the upper-case B to indicate that these sizes are Bytes and not bits?

I am a Mozilla Firefox fan too and I have been using it for the last 6 years or so.I mainly like its extended features and its user friendly interface.

Posted by: Chris C Feb 17, 2010 @ 09:18

Nice, but the function wouldn't return anything if the filesize was bigger than 1024TB. I know it's a silly high number, but perhaps to futureproof it, maybe at the bottom outside the for loop have a return value there of numPB? :)
