Python implements three ways to download files _python

This article mainly introduces the Python implementation of the download file three methods, the most common method is to use the HTTP urllib or URLLIB2 module and requests, interested to understand.

In Python development, the most common way to download files is to use the Urllib or URLLIB2 module via HTTP.

Of course you can also use Ftplib to download files from the FTP site. In addition, Python provides another way to requests.

Here's a look at three ways to download a zip file:

Method One:

Import urllib Import urllib2 import requestsprint "Downloading with urllib" url = ' http://www.jb51.net//test/demo.zip ' pri NT "Downloading with Urllib" Urllib.urlretrieve (URL, "Demo.zip")

Method Two:

Import Urllib2print "Downloading with urllib2" url = ' http://www.jb51.net//test/demo.zip ' F = urllib2.urlopen (URL) data = f . Read () with open ("Demo2.zip", "WB") as Code:     code.write (data)

Method Three:

Import requests print "Downloading with requests" url = ' http://www.jb51.net/test/demo.zip ' r = Requests.get (URL) with open ("Demo3.zip", "WB") as Code:   code.write (r.content)

It seems that using urllib is the simplest, one-sentence statement. Of course you can abbreviate urllib2 into:

f = urllib2.urlopen (URL) with open ("Demo2.zip", "WB") as Code:  code.write (F.read ())
