Python Code Examples

Blog Platform with 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)

                def create_blog_post(title, content):
                    new_post = Post(title=title, content=content)
                    new_post.save()
            
        

Flask Portfolio Website

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

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

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

REST API with Django REST Framework

            
                from rest_framework import serializers, viewsets
                from .models import Book
                
                class BookSerializer(serializers.ModelSerializer):
                    class Meta:
                        model = Book
                        fields = ['id', 'title', 'author', 'published']

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