How to import routes flask

    from flask import Blueprint
    dbscan_handlers = Blueprint('dbscan_handlers', __name__, template_folder='views')

   # Your routes (in the dbscan.py file) will then be something like this
   @dbscan_handlers.route('/xyz/'):
    .....

   @dbscan_handlers.route('/def/'):
    ....

    from controllers.dbscan import dbscan_handlers
    app.register_blueprint(dbscan_handlers)
