Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path

"""
from django.contrib import admin
from django.urls import path
from home.views import *

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', home ,name='home'),
    path('ran_num_gen/', ran_num_gen , name='ran_num_gen' ),
    path('ran_pwd_gen/', ran_pwd_gen ,name='ran_pwd_gen' ),
    path('num_guess_game/', num_guess_game , name='num_guess_game' ),

Home.html：


{% extends 'home\base.html' %}

{% block title %}Welcome to homepage{% endblock title %}

 {% block content %}
 
 <h1>welcome to ALL ABOUT RANDOM</h1> 
 <p>i made this site to learn more about django</p>
 you can do the following things here :
  <hr>
 <li><a href="ran_num_gen/">Random number generator</a></li>
 <hr>
 <li><a href="ran_pwd_gen/">Random password generator</a></li>
 <hr>
 <li><a href="num_guess/">Random guess game</a></li>
 <hr>

i tried changing the name of links and adding the html extensions but it simply did not work.

我尝试更改链接的名称并添加html扩展名，但根本不起作用。

Use forward slashes rather than escape characters:

使用正斜杠而不是转义字符：


e.g.,

例如，


'home\ran_num_gen.html'

...becomes...

...变得...


'home/ran_num_gen.html'

...or...

...或者...


r'home\ran_num_gen.html'
