                        Identify and circle the strings in Python from the following:

                        1. "Name"                           2. 'Delhi'

                        3. 123                              4. 23234.54

                       LIST

                  Lists are a fundamental data structure in  Python  used  to store collections of items. A list is
                  a  sequence  of  multiple  values  in  a  specific  order. In  a  list,  each  element  or  value  is  called  an
                  item. A list  is mutable, which  means the  items in  a list can be  modified  by  assigning  new  values.
                  It  is heterogeneous  in  nature, which  means a list  can contain  numeric  as well  as textual  data.
                  In this chapter, you will learn about creating a list, operations performed on the list, and the functions
                  of the list.

                       CREATING A LIST

                  Python uses lists to store different types of data in a specific order. Since Python lists are changeable
                  types, we can change their elements after they’ve been generated.
                  To create a list, you need to place all the elements separated by a comma inside a square bracket [ ]. The
                  list can contain any number of elements same or different data types such as integer, float, string etc.

                  Syntax to Create a List:

                  <list_name> = [value1, value 2, value 3, ...]

                  An empty list is a list that does not contain any items in it. The example of the empty list is given as
                  follows:
                  To create an empty list:

                  List1 = []

                  Some other examples of the list are given as follows:

                  To create list of 4 integer elements: L1 = [1, 2, 3, 4]
                  To create list of characters: L1 = [’a’, ’b’, ’c’]

                  To create list of 3 strings: L1 = [“Nikhil”, “Dikshant”, “Jatin”]

                  To create list of integer and float numbers: L1 = [1, 1.5, 2.5, 7]

                  To create list with mixed data types: L1 = [7, “Hello”, 3.14]
