Python Flask snippet for serving a file at an endpoint. This snippet demonstrates how to use the `send_file` method to allow users to download a file when they access a specific route.

flask_serve_file.py

from flask import Flask, send_file

app = Flask(__name__)

@app.route('/download-file')
def download_file():
    # Path to the file you want to serve up
    path_to_file = 'path/to/your/file.extension'
    # Serve the file for download
    return send_file(path_to_file, as_attachment=True)

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