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.

Four methods using wget, urllib and request.

#!/usr/bin/python
import requests
from StringIO import StringIO
from PIL import Image
import profile as profile
import urllib
import wget


url = 'https://tinypng.com/images/social/website.jpg'

def testRequest():
    image_name = 'test1.jpg'
    r = requests.get(url, stream=True)
    with open(image_name, 'wb') as f:
        for chunk in r.iter_content():
            f.write(chunk)

def testRequest2():
    image_name = 'test2.jpg'
    r = requests.get(url)
    i = Image.open(StringIO(r.content))
    i.save(image_name)

def testUrllib():
    image_name = 'test3.jpg'
    testfile = urllib.URLopener()
    testfile.retrieve(url, image_name)

def testwget():
    image_name = 'test4.jpg'
    wget.download(url, image_name)

if __name__ == '__main__':
    profile.run('testRequest()')
    profile.run('testRequest2()')
    profile.run('testUrllib()')
    profile.run('testwget()')

testRequest - 4469882 function calls (4469842 primitive calls) in 20.236 seconds

testRequest2 - 8580 function calls (8574 primitive calls) in 0.072 seconds

testUrllib - 3810 function calls (3775 primitive calls) in 0.036 seconds

testwget - 3489 function calls in 0.020 seconds

I use wget.

Simple and good library if you want to example?

import wget

file_url = 'http://johndoe.com/download.zip'

file_name = wget.download(file_url)

wget module support python 2 and python 3 versions
