Introduction to three methods for downloading files using python

During Python development, you may need to download files. The most common method is to use urllib or urllib2 through Http. You can also use ftplib to download files from the ftp site.

You can also use ftplib to download files from the ftp site. In addition, Python provides another requests method.

The following describes how to download a zip file:

Method 1:

import urllib import urllib2 import requestsprint "downloading with urllib" url = 'http://www.pythontab.com/test/demo.zip'  print "downloading with urllib"urllib.urlretrieve(url, "demo.zip")

Method 2:

import urllib2print "downloading with urllib2"url = 'http://www.pythontab.com/test/demo.zip' f = urllib2.urlopen(url) data = f.read() with open("demo2.zip", "wb") as code:         code.write(data)

Method 3:

import requests print "downloading with requests"url = 'http://www.pythontab.com/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 easiest, just a statement. Of course, you can abbreviated urllib2:

F = urllib2.urlopen (url)

With open ("demo2.zip", "wb") as code:

Code. write (f. read ())
