Question

import random
import urllib.request
 def web_image (url):
    name = random.randrange(1, 1000)
    full_name = str(name)+"jpg"
    urllib.request.urlretrieve(url,full_name)

web_image("https://images.pexels.com/photos/67636/rose-blue-flower-rose- blooms-67636.jpeg?auto=format%2Ccompress&cs=tinysrgb&dpr=1&w=500")
