Python Code Examples

Blog Application Example

            
from django.db import models
from django.contrib.auth.models import User

class Post(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
            
        

Online Store Example

            
from flask import Flask, render_template, request
app = Flask(__name__)

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

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

RESTful API Example

            
from rest_framework import viewsets
from .models import Book
from .serializers import BookSerializer

class BookViewSet(viewsets.ModelViewSet):
    queryset = Book.objects.all()
    serializer_class = BookSerializer
            
        

Chat Application Example

            
from flask import Flask, render_template
from flask_socketio import SocketIO

app = Flask(__name__)
socketio = SocketIO(app)

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

if __name__ == '__main__':
    socketio.run(app)
