Erreur d'importation: aucun nom de module urllib2

pour un script fonctionnant avec Python 2 (versions testées 2.7.3 et 2.6.8) et Python 3 (3.2.3 et 3.3.2+) essayer:

#! /usr/bin/env python

try:
    # For Python 3.0 and later
    from urllib.request import urlopen
except ImportError:
    # Fall back to Python 2's urllib2
    from urllib2 import urlopen

html = urlopen("http://www.google.com/")
print(html.read())

ce qui précède n'a pas fonctionné pour moi dans 3.3. Essayez ceci à la place (YMMV, etc)

import urllib.request
url = "http://www.google.com/"
request = urllib.request.Request(url)
response = urllib.request.urlopen(request)
print (response.read().decode('utf-8'))

Python 3:

import urllib.request

wp = urllib.request.urlopen("http://google.com")
pw = wp.read()
print(pw)

Python 2:

import urllib
import sys

wp = urllib.urlopen("http://google.com")
for line in wp:
    sys.stdout.write(line)

bien que j'ai testé les deux Codes dans les versions respectives.

qui a fonctionné pour moi en python3:

import urllib.request
htmlfile = urllib.request.urlopen("http://google.com")
htmltext = htmlfile.read()
print(htmltext)

en python 3, pour obtenir la sortie de texte:

import io
import urllib.request

response = urllib.request.urlopen("http://google.com")
text = io.TextIOWrapper(response)

la plus simple de toutes les solutions:

En Python 3.x:

import urllib.request
url = "https://api.github.com/users?since=100"
request = urllib.request.Request(url)
response = urllib.request.urlopen(request)
data_content = response.read()
print(data_content)
