one notebook to delete elements in AGOL one by one.

This Python code leverages the `arcgis` library to interact with ArcGIS Online. It begins by establishing a session on ArcGIS Online using your credentials (username and password). You'll need to replace `"tu_usuario"` and `"tu_contraseña"` with your actual ArcGIS Online username and password. Next, it identifies a specific Feature Service within ArcGIS Online by its ID, which you should replace with the actual ID of your desired Feature Service. The code then accesses the first layer within this Feature Service and performs a query to retrieve a list of elements from the layer.

Subsequently, it goes through each retrieved element one by one, deleting them individually using the `edit_features` method with the 'deletes' operation. The 'OBJECTID' attribute is used to uniquely identify and remove each element. Finally, it prints a success message to indicate that the elements have been successfully deleted. It's important to ensure that you have the necessary permissions to perform editing operations on the Feature Service you are working with.
