If you want to obtain the contents of a web page into a variable, just read the response of
urllib.request.urlopen
import urllib.request
...
url = 'http://example.com/'
response = urllib.request.urlopen(url)
data = response.read() # a 'bytes' object
text = data.decode('utf-8') # a 'str'; this step can't be used if data is binaryurlretrieve is considered legacy and might become deprecated (not sure why, though).
So the most correct way to do this would be to use the urllib.request.urlopen function to return a file-like object that represents an HTTP response and copy it to a real file using shutil.copyfileobj.
mport urllib.request
import shutil
...
# Download the file from 'url' and save it locally under 'file_name':
with urllib.request.urlopen(url) as response, open(file_name, 'wb') as out_file:
shutil.copyfileobj(response, out_file)
