Python – How to download a file over HTTP


I have a small utility that I use to download an MP3 file from a website on a schedule and then builds/updates a podcast XML file which I've added to iTunes.

The text processing that creates/updates the XML file is written in Python. However, I use wget inside a Windows .bat file to download the actual MP3 file. I would prefer to have the entire utility written in Python.

I struggled to find a way to actually download the file in Python, thus why I resorted to using wget.

So, how do I download the file using Python?

One more, using urlretrieve:

import urllib
urllib.urlretrieve("", "mp3.mp3")

(for Python 3+ use import urllib.request and urllib.request.urlretrieve)

Yet another one, with a "progressbar"

import urllib2

url = ""

file_name = url.split('/')[-1]
u = urllib2.urlopen(url)
f = open(file_name, 'wb')
meta =
file_size = int(meta.getheaders("Content-Length")[0])
print "Downloading: %s Bytes: %s" % (file_name, file_size)

file_size_dl = 0
block_sz = 8192
while True:
    buffer =
    if not buffer:

    file_size_dl += len(buffer)
    status = r"%10d  [%3.2f%%]" % (file_size_dl, file_size_dl * 100. / file_size)
    status = status + chr(8)*(len(status)+1)
    print status,
