This is a real world problem that can be solved with the help of our project. Let’s start the to-do list python project.

Project File Structure

1. Install Django
2. Create an app and a project
3. Settings.py
4. Models.py file
5. Admin.py file
6. Urls.py file
7. Views.py file

1. Install Django :

Django is an open source framework which is used for rapid web development. This framework is written in python. Secure websites are developed with the help of Django. It is mandatory to install django in order to begin the project. To install, run the command given below on cmd or terminal window.

pip install django

2. Create an app and a project:

The next step is to create an app and a project. Create a project named ToDoList and an app home. To store all the html files, create templates folder. Create a template and static folder. Html files are stored in the template folder and all the images and css files are stored in the static folder. To create an app and a project run the command given below on cmd or your terminal window.

python manage.py startapp home

3. Setting.py:

INSTALLED_APPS = [
    'django.contrib.admin',

    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

# Create your models here.
class NewTask(models.Model):
    AddTask=models.CharField(max_length=30)
    time=models.TimeField(auto_now=False, auto_now_add=False)

Code Explanation:
Models.py will help a person in the database connectivity.
a. timezone:It helps to store datetime information in UTC in the database.

Seen by the user.

from django.shortcuts import render,redirect

def saveinfo(request):
    if request.method == "POST":
        AddTask=request.POST['addtask']
        time=request.POST['time']
        add=NewTask(AddTask=AddTask,time=time)
        add.save()
    Add = NewTask.objects.all()
    return render(request,"index.html",{'Add':Add})
def index(request):

def Delete(request,id):
        New = NewTask.objects.get(id=id)
