Do you have experience developing applications using Flask?

Yes, I have experience developing applications using Flask. Flask is a lightweight web framework in Python that allows for quick creation of web applications and APIs. For example, a simple Flask application might look like this:

from flask import Flask, jsonify, request

app = Flask(__name__)

@app.route('/')
def home():
    return "Hello, Flask!"

@app.route('/api/data', methods=['POST'])
def api_data():
    data = request.json
    return jsonify({'received': data})

if __name__ == '__main__':
    app.run(debug=True)

This code creates a server with two routes: the root, which returns a string, and an API that accepts JSON and returns it back. Flask is well-suited for small to medium projects where simplicity and flexibility are important.
