                            LIST

                  In Python, a list is a type of container that is used to store a list of values of any type. One can
                  store an integer, string as well as objects in a single list. Each element in a list is assigned an index
                  number. The first index is 0, the second index is 1, the third is 2, and so on.


                  CREATING A LIST
                  Lists can be created by inserting the elements in square brackets []. The elements in the list are
                  separated by a comma.
