Preface

I recently updated the Python version and was going to write a crawler. I unexpectedly found that the attribute urlopen did not exist in the urllib library, so I googled it and summarized the solution.

The occurrence of the problem

AttributeError: 'module' object has no attribute 'urlopen '

Solution to the problem

Let's first look at the explanation of the official document:

a new urllib package was created. It consists of code from 
urllib, urllib2, urlparse, and robotparser. The old 
modules have all been removed. The new package has five submodules: 
urllib.parse, urllib.request, urllib.response, 
urllib.error, and urllib.robotparser. The 
urllib.request.urlopen() function uses the url opener from 
urllib2. (Note that the unittests have not been renamed for the 
beta, but they will be renamed in the future.)

That is to say, the official version 3.0 has integrated urllib2, urlparse and other five modules into urllib, that is, integrated.

Correct usage

import urllib.request 
url="http://www.baidu.com" 
get=urllib.request.urlopen(url).read() 
print(get)
