how to solve "NameError: name 'pages' is not defined"

I was trying to print “hello world” with Django but the powershell says ’ path(“”,include(pages.urls)) NameError: name ‘pages’ is not defined ', I did exactly everything the book “Django for beginners” on chapter two told me:(LearnDjango | LearnDjango.com). I don’t know how to debug at all

I’m a newbie to web development and Django is my first choice, I just imported things like django.x.y.z without knowing what really happens deep there and how things connect to each other, it feels so frustrating and overwhelming, could someone help me pls?

Post the contents of your urls.py file(s).

Put three backticks ``` on a line before and after each code block so that they format correctly.
