use the The ExampleInsert an item as the second position: thislist = ["apple", "banana", "cherry"] Try it Yourself » Note: As a result of the examples above, the lists will now contain 4 items. Extend ListTo append elements from another list to the current list, use the ExampleAdd the elements of thislist = ["apple", "banana", "cherry"] Try it Yourself » The elements will be added to the end of the list. Add Any IterableThe ExampleAdd elements of a tuple to a list: thislist = ["apple", "banana", "cherry"] Try it Yourself » In this tutorial, we will learn different ways to add elements to a List in Python.

4. List ConcatenationIf you have to concatenate multiple lists, you can use the “+” operator. This will create a new list and the original lists will remain unchanged.
The new list will contain elements from the list from left to right. It’s similar to the string concatenation in Python. ConclusionIt’s very easy to add elements to a List in Python programming.
