python urllib error

Question

so I have this code:

def crawl(self, url):
    data = urllib.request.urlopen(url)
    print(data)

but then when I call the function, it returns

    data = urllib.request.urlopen(url)
AttributeError: 'module' object has no attribute 'request'

what did I do wrong? I already imported urllib..

using python 3.1.3

Answer 1

In python3, urllib is a package with three modules request, response, and error for its respective purposes.

Whenever you had import urllib or import urllib2 in Python2. Replace them with

import urllib.request
import urllib.response
import urllib.error

The classs and methods are same.

BTW, use 2to3 tool if you converting from python2 to python3.

Answer 2

urllib.request is a separate module; import it explicitly.
