Flask is perfect for building lightweight APIs, and Python’s requests library makes it easy to communicate with those APIs. Here’s a quick example:
from flask import Flask, request, jsonify
app = Flask(__name__)
@app.route('/greet', methods=['POST'])
def greet():
data = request.get_json()
name = data.get('name', 'Guest')
return jsonify({'message': f'Hello, {name}!'})
if __name__ == '__main__':
app.run(debug=True)
Client (sending data using requests):
import requests
response = requests.post(
'http://127.0.0.1:5000/greet',
json={'name': 'Alex'}
)
print(response.json())
This setup is ideal for internal tools, microservices, or learning to interact with REST APIs. Always validate and secure incoming data for production use.
