Python Code Examples

            
# Example code for a simple Flask API
from flask import Flask, jsonify, request

app = Flask(__name__)

tasks = []

@app.route('/tasks', methods=['GET'])
def get_tasks():
    return jsonify(tasks)

@app.route('/tasks', methods=['POST'])
def add_task():
    task = request.json
    tasks.append(task)
    return jsonify(task), 201
    
if __name__ == '__main__':
    app.run(debug=True)
            
        

Real-World Applications

Python web development has numerous practical applications across various domains:

• Content Management Systems: Many popular content management systems like Django CMS and Wagtail are built on Python, enabling users to create and manage digital content easily.
• Data Analysis Platforms: Websites that offer data analysis tools or dashboards typically use Python on the server-side for processing and visualization, such as with Flask applications integrating Pandas and Matplotlib.
• Social Media Applications: Python frameworks are often used to build social networking sites, allowing user interactions, data sharing, and real-time features.
• eLearning Platforms: Python is widely utilized in educational platforms for handling user data, course management, and media streaming.
• Gaming Websites: Online gaming platforms and leaderboard systems can be built using Python web frameworks to manage user profiles and game statistics efficiently.
