The explanation is easy: If we use the append method, we will simply append a further element to the list in each loop pass. This method does not return any value but updates existing list. Now we come to the first loop, in which we use l = l + [i * 2]. Add a list to a list: a = ["apple", "banana", "cherry"] b = ["Ford", "BMW", "Volvo"] a.append (b) Try it Yourself ». Add an element to the end of python list. Syntax of index() function: list.insert(position, element) It accepts two parameters, first is the position of the element and second one is element to inserts the element at a given position in the list. Next, iterate the for loop and add the number in the list. If you want to get the single element of the list in Python. for exercises and resources. Get Single List Element By Index in Python. To find an element in the Python list, use one of the following approaches. Syntax of append method. The pop() removes the last element from the list but only the single one. Index operator. It is the simplest approach in Python to add two list elements. But, if we want to add an element at specified index, we use insert() method.
