4 lines in each code ! But yes, when (like in the example) you want to login to a website, thats annother thing... URLLIB is great for little things if you cant download Requests. Requests is really better because Python code with Requests its a lot more human-readable.

Yes, that's the point of @kennethreitz's examples. Operations that are complicated with urllib are simple with requests.

Unfortunately, code to format an url with requests is longer and more bloated than urllib:

# requests
from requests import Request
url = Request(None, 'http://example.com/?', params={'Data1': 'data'}).prepare().url

# urllib
import urllib
url = 'http://example.com/?' + urllib.parse.urlencode({'Data1': 'data'})

Just read this: https://stackoverflow.com/a/46783596
You can just use requests.utils (and other submodules, I've seen annother one for functions included in urllib.parse but I don't remember it) instead of urllib.parse in most cases I think.
(and it does not requires requests.utils to be imported because importing requests also imports requests.utils)
NOTE: The functions are comming right from the URLLIB package, so the actual documentation is in URLLIB for some (not all) of the function of this submodule of requests.
