Python Code Examples
Example Code for Blog Application using Django
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 Code for RESTful API with Flask
from flask import Flask, jsonify, request
app = Flask(__name__)
items = []
@app.route('/items', methods=['GET'])
def get_items():
return jsonify(items)
@app.route('/items', methods=['POST'])
def add_item():
item = request.json.get('item')
items.append(item)
return jsonify({"message": "Item added!"}), 201
if __name__ == '__main__':
app.run(debug=True)
Real-World Applications
Python web development is widely used in various real-world applications across different industries. For instance:
- Social Media Platforms: Websites such as Instagram utilize Python extensively for their backend services to manage user data and serve dynamic content.
- Financial Services: Companies often use Python frameworks to create secure web applications that manage transactions, customer interactions, and data analysis.
- Content Management Systems: Many popular CMS systems are built using Django, enabling users to manage page content easily and publish updates.
