How about using numpy?

to_be_deleted is an array of indexes to be deleted from myList. You seem to 
already have that list created but your list is contiguous. Just in case it 
isn't, you can say stuff like:

to_be_deleted = numpy.where( myList > allowed_or_something )
myList = numpy.delete( myList, to_be_deleted )
