I need to check, inside a Python script, if an object with a
particular ID exists inside a folder.
    Right now I'm using the following code:

    # this is the folder I want to search
    myFolder = container.REQUEST.PARENTS[0].img_folder

    # search the folder for an object with ID <object_id>
    obj = getattr(myFolder, object_id, None)
    if obj is not None:
        # there is no such object
    else:
        # there is an object with that id
 

    Is there a more efficient way to perform this operation?
 

kind regards,
