Django

I am doing Cs50web course and working on a project using Django. I have created a path in urls.py of application and it has two requests, Get and Post.
It's a form page where you can add the Title, Content and a button to save:

On encyclopedia/newpage as get request page gets open and on http://<ip>/encyclopedia/newpage url as a post request page get saved. However, When page is open in the browser as http://127.0.0.1:80000/encyclopedia/newpage by clicking the
Save button, the url becomes http://127.0.0.1:80000/encyclopedia/newpage/newpage and shows an error.

{% extends "encyclopedia/layout.html" %}

{% block body %}
    <h1>Create New Page</h1>
    <form action="newpage/" method="post">
        {% csrf_token %}
        <input type="text" name="title" id="title_box" 
        placeholder="Enter title">

        <button type="submit" name="save" 
        class="btn btn-primary">Save</button>

            alert("{{ message }}");
