Python (25) Download file

It's interesting to use the program to write your own downloads. The most popular method in Python is to use Urllib or URLLIB2 modules over HTTP. Of course you can also use Ftplib to download files from the FTP site. In addition, Python provides another way to requests.

Take a look at three ways to download a zip file:

import urllibimport urllib2import requests URL='Http://www.blog.pythonlibrary.org/wp-content/uploads/2012/06/wxDbViewer.zip'#如果你下载的文件是rar, the following will be replaced by. rar, download txt is replaced by. txt, print"Downloading with urllib"urllib.urlretrieve (URL,"Code.zip") Print"Downloading with urllib2"F=urllib2.urlopen (URL) data=F.read () with open ("Code2.zip","WB") ascode:code.write (data) Print"downloading with requests"R= requests.Get(URL) with open ("Code3.zip","WB") asCode:#.zip is based on the file format, this place only played the role of renaming Code.write (r.content) seems to use urllib the simplest, a sentence can be. Of course you can abbreviate urllib2 to: F= Urllib2.urlopen (URL) with open ("Code2.zip","WB") asCode:code.write (F.read ())
