PY🔹 Reverse a String Without Slicing in Python 🔹
Instead of using the shortcut [::-1], we can reverse a string step by step using a for loop with range() in reverse order.
👉 How it works:
len(s)-1 gives the last index of the string.
range(len(s)-1, -1, -1) iterates from the last index down to 0.
Each character is added to reversed_str in reverse order.
✅ Output for s = "hello" → olleh

COFlask 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
