Inserting data into an array used to be one of the most inefficient operations you could perform in programming. This is because if the array is large, and the insertion was towards the beginning of the array, you would have to shift a large number of array elements to the right to make room for the inserted data.

Now, with a more modern array (list in Python) functions, this task is not so difficult as the shifting is performed behind the scenes for you. In this article, I’m going to discuss how to insert new data into a Python list using existing Python methods.
