deleteOne list , value
Description

also
deletes the property associated with the deleted value. If the value appears in the list more than
once,

deletes only the first occurrence.
Attempting to delete a property has no effect.

The first statement creates a list consisting of the days Tuesday, Wednesday, and Friday. The
second statement deletes the name Wednesday from the list.
days = ["Tuesday", "Wednesday", "Friday"]
days.deleteOne("Wednesday")
put days
The
put days
statement causes the Message window to display the result:
-- ["Tuesday", "Friday"].
deleteProp
Usage
list .deleteProp( item )
deleteProp list , item
Description
List command; deletes the specified item from the specified list.
•
For linear lists, replace
item
with the number identifying the list position of the item to be
deleted. The
deleteProp
command for linear lists is the same as the
deleteAt
command. If
the number is greater than the number of items in the list, a script error occurs.
•
For property lists, replace
item
with the name of the property to be deleted. Deleting a
property also deletes its associated value. If the list has more than one of the same property,
only the first property in the list is deleted.
Parameters
item
Required. The item to delete from the list.
Example
This statement deletes the color property from the list [#height:100, #width: 200, #color: 34,
#ink: 15], which is called spriteAttributes:
spriteAttributes.deleteProp(#color)
The result is the list [#height:100, #width: 200, #ink: 15].
