Python question: Importing modules the purpose of "."

Question

Hi,

Online, I saw this
import urllib.request
Is this having two libraries being imported together?

Eg What is the difference between
import urllib.request

vs

import urllib
import request

Answer 1

urllib is a package and urllib.request is one of the four modules in that package. The documentation fir the urllib package can be found here: https://docs.python.org/3/library/urllib.html

Answer 2

If you would like to import the entire package, I believe you can just do:
import urllib

Answer 3

urllib.request is a single word. Its the name of a python module that is used to open urls.

Answer 4

Ohh right, then is there a difference between urllib vs urllib.request?

Answer 5

ok, if I import just urllib then would i get all the four modules? or I need to import all the modules separately?

Answer 6

import urllib.request
OR
from urllib import request
are the same
