47. Problem to insert a given string at the beginning of list elements.

In this Python list program, we will take a user input as a list and insert the given string at the beginning of the list elements with the help of the below-given steps.

Insert a string at the beginning of list elements:

Steps to solve the program

Take a list as input.
