Python download files

A. download files using Urllib

Import url lib
url= ' http://www.pythontab.com/test/demo.zip '
url lib.urlretrieve (url, ' demon ')

Two. download files using requests

Import requests
url= ' Http://www.pythontab.com/test/demo.zip '
r=requests.get (URL) with
open (' Demo.zip ', ' WB ') as Code:
    code.write (r.content)

Three. download files using Urllib2

Import urllib2
url= ' http://www.pythontab.com/test/demo.zip '
f=urllib2.urlopen (URL)
data=f.read ()
with open (' Demo.zip ', ' WB ') as Code:
    code.write (data)

Explain:
The above three methods download files: Urllib directly download the file, while requests and urllib2 are reading the contents of the file, and then save the content to the file.
