Downloading Large Files -- Feedback?

[mwt]

So, I just put this little chunk to the test, which does give you
feedback about what's going on with a file download. Interesting that
with urlretrieve, you don't do all the file opening and closing stuff.

Works fine:

------------------
import urllib

def download_file(filename, URL):
    f = urllib.urlretrieve(URL, filename, reporthook=my_report_hook)

def my_report_hook(block_count, block_size, total_size):
    total_kb = total_size/1024
    print "%d kb of %d kb downloaded" %(block_count *
(block_size/1024),total_kb )

if __name__ == "__main__":
   download_file("test_zip.zip","http://blah.com/blah.zip")
