You need to install to mysqlclient to connect to mysql (wampserver).
For install mysqlclient you need to Visual C++ 2015 Build Tools. Use below link to download visualstudio tool. http://go.microsoft.com/fwlink/?LinkId=691126&fixForIE=.exe.
Now you need to set your visual studio path in path variable by using below command in commandline.
“setx path "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC"”

Now you need to install mysqlclient by using below command
“pip install mysqlclient”

If you found error like “MySQLdb/_mysql.c(29): fatal error C1083: Cannot open include file: 'mysql.h': No such file or directory
    error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\cl.exe' failed with exit status 2”

so you need to download .whl file for direct install, You can use below link to download as per your system compatibility.
“https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclient.Then”
“mysqlclient-1.4.2-cp37-cp37m-win32.whl” file work for me.

 “pip install mysqlclient-1.4.2-cp37-cp37m-win32.whl”

Mysqlclient is install now!!

You need to change setting.py according to mysql
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'learnpython',
        'USER': 'nilesh',
        'PASSWORD': 'Radhe@12',
        'HOST': 'localhost',
        'PORT': 3306
    }
}

Enjoy now Django is connect with mysql!!

Create template in Django python

For using templates we need to modify in setting.py
TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR,'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]
'templates' is name of your templates directory. It must be at your root directory.
Template file will be your html file. Create template html file in template directory.
How to include CSS/JS in your template file.
        Define your static directory named as “staticFiles” in your project.
        STATIC_URL = '/static/'
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'staticFiles'),
)
In your html template how to use static directory files.
Include {% load static %} for loading static directory in template file.
Use <script type="text/javascript" src="{% static "jquery.min.js" %}"></script> to include java-script file.
Enjoy your first template!!
For using layout of web-site you need to create a layout.html in templates directory.
This layout.html contain the layout. That file need to be include in page view file.
In views.py file you need to define function like.
def main(request):
        variables = {
        'variable_1': 'Value of variable one',
        'variable_2': 'Value of variable two'
    }
        return render(request, "main.html", context=variables )
So your main page will call main.html. which contain
{% extends "layout.html" %}

{% block content %}
  <H1>Main body part</H1>
  <p>{{ variable_1 }}</p>
  <p>{{ variable_2 }}</p>
{% endblock %}

Here we extent layout.html in main.html. here layout.html is web-site layout.
It contain.
<!DOCTYPE html>
<html>
  <head>
    <title>First App</title>
    {% load static %}
    <link rel="stylesheet" href="{% static "/bs3.4.1/css/bootstrap.min.css" %}">
    <link rel="stylesheet" href="{% static "/layout.css" %}">
    <script type="text/javascript" src="{% static "/bs3.4.1/js/bootstrap.min.js" %}"></script>
    <script type="text/javascript" src="{% static "jquery.min.js" %}"></script>
  </head>
  <body>
    <div class="container container-table">
      <div class="row header" >
        <div class="col-md-2">md2</div>
        <div class="col-md-8">md8</div>
        <div class="col-md-2">md2</div>
      </div>
      <div class="row bodyContainer col-md-12" >
        {% block content %}{% endblock %}
      </div>
      <div class="row footer" >
        <div class="col-md-2"></div>
        <div class="col-md-8" align="center">Footer</div>
        <div class="col-md-2"></div>
      </div>
    </div>
  </body>
</html>

Enjoy your first page with basic website layout.
