Make a blank page under django

To build a web page, you need to configure the environment first. The specific environment configuration such as pyenv, python, etc. will not be introduced too much here. Here's a primer on how to build web pages with django.
Please make sure that pyenv and python have been configured for the following codes, and the following codes are all run in the terminal.

mkdir demo //Create a demo folder
cd demo //Enter the folder
python3 -m venv myvenv// Create a virtual environment
source myvenv/bin/activate //Enter the virtual environment
pip install django==1.8 //Configure django under the virtual environment
django-admin startproject mysite .//Create a project folder, mysite

Open the setting.py file in mysite and change TIME_ZONE to Asia/Shanghai. Then add at the bottom of this file

STATIC_ROOT = os.path.join(BASE_DIR, 'static')

After running the database,

python manage.py migrate // configure the database (these codes run in the terminal)
python manage.py runserver//run database

Here, the URL 127.0.0.0.1:8000 can be opened initially, but there is no content.
At this time, we need to write a web page, where to write it? Please see below:
First you need to change the url

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),//Add this link,
    url(r'', include('demo.urls')),]

Then create the demo folder, and create the urls.py file and add in this file:

from django.conf.urls import url
from .import views//import

Then create the two folders templates/demo in the demo file, and create the list.html file in the demo file. At
this time, you will find a blank page when you open the web page again. Use your knowledge of html and css if you need to display something. This article does not introduce too much.
