The urllib module has been split into parts and renamed in Python 3 to urllib.request, urllib.parse, and urllib.error.

Import urllib.request instead of urllib.

import urllib.request

Interestingly, I noticed some IDE-depending behavior.

Both Spyder and PyCharm use the same interpreter on my machine : in PyCharm I need to do

import urllib.request

while in Spyder,

import urllib

does fine

If this is on PyCharm, as was mine, make sure your file name isn't urllib.py.

In visual code , u have to write import urllib.request instead of just import urllib.
Also, whenever errors such as module x has no attribute y occurs, it's because you have named the current file same as the package you are trying to import.
So, the way import in python works is that it first searches the current dir, and if it finds the module/package 'x' u were looking for , it assumes that it has found the target file, and searches for 'y'. And since u haven't defined 'y', the aforementioned error occurs.
