Python Code Examples

        
            # Example code for a simple Flask application (Personal Blog Site)
            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)

        
            # Example code for a basic web scraping application
            import requests
            from bs4 import BeautifulSoup

            URL = 'https://example.com'
            page = requests.get(URL)
            soup = BeautifulSoup(page.content, 'html.parser')
            print(soup.prettify())

        
            # Example code for a simple RESTful API using 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
                items.append(item)
                return jsonify(item), 201
