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

I'm trying to use Python to download the HTML source code of a website but I'm receiving this error.

Traceback (most recent call last):  
    File "C:\Users\Sergio.Tapia\Documents\NetBeansProjects\DICParser\src\WebDownload.py", line 3, in <module>
     file = urllib.urlopen("http://www.python.org")
AttributeError: 'module' object has no attribute 'urlopen'

I'm following the guide here: http://www.boddie.org.uk/python/HTML.html

import urllib

file = urllib.urlopen("http://www.python.org")
s = file.read()
f.close()

#I'm guessing this would output the html source code?
print(s)

I'm using Python 3.

Change TWO lines:

import urllib.request #line1

#Replace
urllib.urlopen("http://www.python.org")
#To
urllib.request.urlopen("http://www.python.org") #line2

If You got ERROR 403: Forbidden Error exception try this:

siteurl = "http://www.python.org"

req = urllib.request.Request(siteurl, headers={'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.100 Safari/537.36'})
pageHTML = urllib.request.urlopen(req).read()

I hope your problem resolved.

For python 3, try something like this:

import urllib.request
urllib.request.urlretrieve('http://crcv.ucf.edu/THUMOS14/UCF101/UCF101/v_YoYo_g19_c02.avi', "video_name.avi")

It will download the video to the current working directory

I got help from HERE

Solution for python3:

from urllib.request import urlopen

url = 'http://www.python.org'
file = urlopen(url)
html = file.read()
print(html)

If your code uses Python version 2.x, you can do the following:

from urllib.request import urlopen
urlopen(url)

By the way, I suggest another module called requests, which is more friendly to use. You can use pip install it, and use it like this:

import requests
requests.get(url)
requests.post(url)
import urllib
import urllib.request
from bs4 import BeautifulSoup


with urllib.request.urlopen("http://www.newegg.com/") as url:
    s = url.read()
    print(s)
soup = BeautifulSoup(s, "html.parser")
all_tag_a = soup.find_all("a", limit=10)

for links in all_tag_a:
    #print(links.get('href'))
    print(links)

One of the possible way to do it:

import urllib
...

try:
    # Python 2
    from urllib2 import urlopen
except ImportError:
    # Python 3
    from urllib.request import urlopen

Use the third-party six module to make your code compatible between Python2 and Python3.

from six.moves import urllib
urllib.request.urlopen("<your-url>")
imgResp = urllib3.request.RequestMethods.urlopen(url)

Add this RequestMethods before using urlopen
