#Flask Web Development Tutorial

Flask 2.0 is a lightweight web framework in Python that allows you to create APIs quickly and efficiently. Let’s go step by step to build a simple REST API. Step 1: Install Flask First, ensure you have Flask installed. You can install it using pip: pip install flask Step 2: Create a Basic Flask API Create a new Python file, e.g., app.py, and add the following code: from flask import Flask, jsonify, request app = Flask(__name__) # Sample data (like a mini-database) users = [ {"id": 1, "name": "Alice"}, {"id": 2, "name": "Bob"} ] # Route to get all users @app.route('/users', methods=['GET']) def get_users(): return jsonify(users) # Route to get a specific user by ID @app.route('/users/<int:user_id>', methods=['GET']) def get_user(user_id): user = next((u for u in users if u["id"] == user_id), None) return jsonify(user) if user else ("User not found", 404) # Route to create a new user @app.route('/users', methods=['POST']) def create_user(): data = request.json new_user = {"id": len(users) + 1, "name": data["name"]} users.append(new_user) return jsonify(new_user), 201 # Route to update a user @app.route('/users/<int:user_id>', methods=['PUT']) def update_user(user_id): data = request.json user = next((u for u in users if u["id"] == user_id), None) if user: user["name"] = data["name"] return jsonify(user) return "User not found", 404 # Route to delete a user @app.route('/users/<int:user_id>', methods=['DELETE']) def delete_user(user_id): global users users = [u for u in users if u["id"] != user_id] return "User deleted", 200 # Run the Flask app if __name__ == '__main__': app.run(debug=True) Step 3: Run Your Flask API Run the script: python app.py You should see output like: * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit) Step 4: Test Your API You can test the API using Postman or cURL. Get all users: curl http://127.0.0.1:5000/users Get a specific user: curl http://127.0.0.1:5000/users/1 Create a new user: curl -X POST -H "Content-Type: application/json" -d '{"name": "Charlie"}' http://127.0.0.1:5000/users #python #programming #coding

“flask” (REST server) in Python #coding #programming #python #kabirstack #flask #restserver

Implemento a condição if name == "main" no Flask para garantir que o servidor web seja iniciado apenas quando o arquivo principal for executado diretamente. Esta é uma boa prática essencial em Python que evita a execução automática do servidor caso o script seja importado como um módulo em outros arquivos. Mostro a diferença na estrutura do código e como isso mantém a aplicação organizada e segura para ambientes de produção e desenvolvimento. #Python #Flask #Programacao
