I have tried
import urllib.request
or
import urllib
The path for my urllib is
/Library/Framework
If nothing above worked for you, try renaming your python module.
In my particular case, the issue was that the file I was running was called http.py. Once I changed the name to test-http.py, importing urllib.request resolved the error AttributeError: module 'urllib' has no attribute 'request'
I had noticed that further up the exception trace the internal packages were trying to fetch a module called http, so guessing my module's name was wonkin stuff up...
