django

Think of a college. It's a huge building with many classrooms and departments. You want to find your class, so you approach the receptionist and ask, "Where can I find the I Year ECE class?" The receptionist checks the information and directs you to the correct classroom.

In a similar way, when you request a URL such as /videosnap/account/ through your browser, Django's URL resolver acts like the receptionist. It looks at the URL you requested and directs that request to the appropriate view, which handles the request and sends a response back to the browser and college buliding mapis similar to URLConf.        
 

URL → Uniform Resource Locator

A URL is like an address on the internet ,It tells the browser where to find or request something.
Django allows us to define and customize our own URLs with the help of URLConf.
URLConf the name itself suggest's URL Configuration it is where we define urlpatterns for django applications and map them to views.This configuration is done in "urls.py" using path() function and pass a few arguments to this function. 

For example 

from django.urls import path
 urlpatterns=[
path("accounts/",views.profile,name="accounts"),

path("posts/",views.create_post,name="create_post"),

]
So here      “accounts/” → route

                    views.profile → It is the view(function) associated to the route “accounts/” 
                    name → Naming your URL lets you refer to it unambiguously from elsewhere in Django,                                              especially from within templates. This powerful feature allows you to make global                                        changes to the URL patterns of your project while only touching a single file.
So whenever we request www.videosnap.com/accounts/, Django receives the request, checks the requested URL against the URL patterns defined in URLconf, and if a matching pattern is found, Django calls the corresponding view."
Django URLs Functions

Django URLs function handles the user request and maps the request to respective views. Let's discuss the important django.urls function in detail:
