Preface

I recently updated the Python version and was preparing to write a crawler. unexpectedly, I found that the urllib library does not contain urlopen. Therefore, I would like to summarize all kinds of google and provide a solution.

Problem

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

Solution

Let's take a look at the explanation in 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, integration.

Correct usage

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

Result:

In fact, we can change the UTF-8 encoding to make the source code read more correct, but this is not mentioned anymore.
