Python urllib urlopen not working

Question

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         


        

Answer 1

For python 3 the correct way should be:

import cv2
import numpy as np
import urllib.request

req = urllib.request.urlopen('http://answers.opencv.org/upfiles/logo_2.png')
arr = np.asarray(bytearray(req.read()), dtype=np.uint8)
img = cv2.imdecode(arr, -1) # 'Load it as it is'

cv2.imshow('image_name', img)
if cv2.waitKey() & 0xff == 27: quit()

Here you can find the documentation related to urllib.request

Answer 2

import requests
import urllib

link = "http://www.somesite.com/details.pl?urn=2344"

f = urllib.request.urlopen(link)
myfile = f.read()

writeFileObj = open('output.xml', 'wb')
writeFileObj.write(myfile)
writeFileObj.close()
