Python Code Examples

Example 1: Simple Flask App

            
from flask import Flask

app = Flask(__name__)

@app.route('/')
def home():
    return "Welcome to My Portfolio!"

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

Example 2: Basic Django Model

            
from django.db import models

class Post(models.Model):
    title = models.CharField(max_length=200)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.title
            
        

Example 3: Creating a RESTful API with Flask

            
from flask import Flask, jsonify

app = Flask(__name__)

@app.route('/api/data')
def get_data():
    return jsonify({"message": "Hello, World!"})

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