Basic http file downloading and saving to disk in python?

A clean way to download a file is:

import urllib

testfile = urllib.URLopener()
testfile.retrieve(http://randomsite.com/file.gz, file.gz)

This downloads a file from a website and names it file.gz. This is one of my favorite solutions, from Downloading a picture via urllib and python.

This example uses the urllib library, and it will directly retrieve the file form a source.

As mentioned here:

import urllib
urllib.urlretrieve (http://randomsite.com/file.gz, file.gz)

EDIT: If you still want to use requests, take a look at this question or this one.

For Python3+ URLopener is deprecated.
And when used you will get error as below:

url_opener = urllib.URLopener() AttributeError: module urllib has no
attribute URLopener

So, try:

import urllib.request 
urllib.request.urlretrieve(url, filename)
