The <pop> block removes an element at a specific index from a list while returning the element to be removed; it directly references the Python function: .pop()
See the Python documentation for more details.
•« list » : The variable from which you want to remove an element; the default value is an empty list.
•« index » : The index in the list pointing to the element to be removed
•« list » : This is the list without the removed element, the type is defined by the “list” input
•« elem » : The removed element
The “list” input and output are of type list
The “index” input is of type int
The “elem” input can be of any type
Since “elem” = “list”input.pop(“index”), after the block executes, the two lists are identical.
