I am just trying to fetch data from a live web by using the urllib module, so I wrote a simple example

Here is my code: 

import urllib

sock = urllib

    I just queried the same question which is now over 5 years old.

    Please note that the URL given is also old, so i substituted the python welcome page.

    We can use the requests module in python 3.

    I use python 3 and the solution is below:

    import requests

r = requests.get('https://www.python.org/')
t = r.text

print(t)

    This works and is clean.

    In Python3 you can use urllib or urllib3

    urllib:

    import urllib.request
with urllib.request.urlopen('http://docs.python.org') as response:
    htmlSource = response.read()

    urllib3:

    import urllib3
http = urllib3.PoolManager()
r = http.request('GET', 'http://docs.python.org')
htmlSource = r.data

    More details could be found in the urllib or python documentation.

    Use this import cv2 import numpy as np import urllib //import urllib using pip import requests // import requests using pipenter code here url = "write your url" while True: imgresp = urllib.request.urlopen(url) imgnp = np.array(bytearray(imgresp.read()),dtype=np.uint8) img = cv2.imdecode(imgnp,-1) cv2.imshow("test",img) cv2.waitKey('q')

    This is what i use to get data from urls, its nice because you could save the file at the same time if you need it:

    import urllib

result = urllib.urlretrieve("http://diveintopython.org/")

print open(result[0]).read()

    output:

    '<!DOCTYPE html><body style="padding:0; margin:0;"><iframe src="http://mcc.godaddy.com/park/pKMcpaMuM2WwoTq1LzRhLzI0" style="visibility: visible;height: 2000px;" allowtransparency="true" marginheight="0" marginwidth="0" frameborder="0" scrolling="no" width="100%"></iframe></body></html>'

    Edit: urlretrieve works in python 2 and 3

    You are reading the wrong documentation or the wrong Python interpreter version. You tried to use the Python 3 library in Python 2.

    Use:

    import urllib2

sock = urllib2.urlopen("http://diveintopython.org/") 
htmlSource = sock.read()                            
sock.close()                                        
print htmlSource

    The Python 2 urllib2 library was replaced by urllib.request in Python 3.

    Make sure you import requests from urllib, then try this format, it worked for me:

    from urllib import request
urllib.request.urlopen( )
