Python Code Examples

Blogging Platform Example

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

            class Post(models.Model):
                title = models.CharField(max_length=200)
                content = models.TextField()
                author = models.ForeignKey(User, on_delete=models.CASCADE)
                created_at = models.DateTimeField(auto_now_add=True)

                def __str__(self):
                    return self.title

E-commerce Website Example

        
            from flask import Flask, render_template

            app = Flask(__name__)

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

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

Portfolio Website Example

        
            from django.urls import path
            from . import views

            urlpatterns = [
                path('', views.home, name='home'),
                path('projects/', views.projects, name='projects'),
            ]
