Python Web Development Projects and Applications

Key Projects

• Personal Blog Website: Create a personal blogging platform using Flask, allowing users to create, edit, and delete blog posts. This project can help beginners understand the concepts of routing, templates, and databases.
• Todo List Application: Build a simple Todo list manager with Django that allows users to add, update, and delete tasks. This project emphasizes CRUD (Create, Read, Update, Delete) operations.
• E-commerce Store: Develop a basic e-commerce application using Django, complete with products, cart functionality, and user authentication. This project introduces a more complex structure and user interactions.

Python Code Examples

Example 1: Simple Flask Application

            
from flask import Flask, render_template, request, redirect

app = Flask(__name__)

@app.route('/')
def home():
    return render_template('home.html')

@app.route('/submit', methods=['POST'])
def submit():
    # Handle form submission
    return redirect('/')

if __name__ == '__main__':
    app.run(debug=True)
            
        

Example 2: Basic Django Todo List

            
from django.shortcuts import render, redirect
from .models import Task

def todo_list(request):
    tasks = Task.objects.all()
    return render(request, 'todo_list.html', {'tasks': tasks})

def add_task(request):
    if request.method == 'POST':
        task = request.POST.get('task')
        Task.objects.create(name=task)
        return redirect('todo_list')
