deleteOne

Syntax

list.deleteOne(value)
deleteOne list, value

Description

Attempting to delete a property has no effect.

Example

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"].
