Python Code Examples

Blog Platform (Django)

            
from django.db import models

class Post(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)

class Comment(models.Model):
    post = models.ForeignKey(Post, related_name='comments', on_delete=models.CASCADE)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)
            
        

To-Do List Application (Flask)

            
from flask import Flask, render_template, request, redirect

app = Flask(__name__)
tasks = []

@app.route('/')
def index():
    return render_template('index.html', tasks=tasks)

@app.route('/add', methods=['POST'])
def add_task():
    task = request.form['task']
    tasks.append(task)
    return redirect('/')
            
        

Real-World Applications

Python web development is widely recognized for its versatility in various domains. Here are a few real-world applications:
