List Append. Introduction¶. The list subcommands APPEND, INSERT, FILTER, PREPEND, POP_BACK, POP_FRONT, REMOVE_AT, REMOVE_ITEM, REMOVE_DUPLICATES, REVERSE and SORT may create new values for the list within the current CMake variable scope. Similar to the set() command, the LIST command creates new variable values in the current scope, even if the list itself is actually defined in a parent scope. How to append list to second list (concatenate lists) in Python? How to append objects in a list in Python? Insert an element at second position in a C# List; How to initialize a list to an empty list in C#? C# program to find Largest, Smallest, Second Largest, Second Smallest in a List; Java Program to Append Text to an Existing File Python – Append List to Another List – extend() To append a list to another list, use extend() function on the list you want to extend and pass the other list as argument to extend() function.. In this tutorial, we shall learn the syntax of extend() function and how to use this function to append a list to other list.

On a more traditional note, folks who want to add an item to the end of a list in Python can rely on append: my_list = [] my_list.append(5) Each call to append will add one additional item to the end of the list. In most cases, this sort of call is made in a loop.
Append to a Scala List. From a performance stand point, if you want to add items to the list use the prepend option. Appending means you are adding an element to the end of the list and it is not an efficient operation. But in case the list is small and the performance impact is negligible then the :+ method can be used.
Description. Python list method append() appends a passed obj into the existing list.. Syntax. Following is the syntax for append() method −. list.append(obj) Parameters. obj − This is the object to be appended in the list.. Return Value.
