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

                 To create 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]

                 Program 1: To print the different types of lists


                     Program1.py
                  File  Edit  Format   Run   Options   Window     Help

                  new_list1=[5, 6, 7, 8]                     #Homogeneous data elements
                  print(new_list1)

                  new_list2=[5, "Orange", 15.5]              #Heterogeneous data elements
                  print(new_list2)





                 On running the above program, you will get the following output:

                     Output

                  [5, 6, 7, 8]
                  [5, 'Orange', 15.5]




                 Nested List

                 A list that contains another list in it, is called a nested list. The example of the nested list is given as follows:
                 To create nested list: L1 = [’Orange’, 2.0, 5, [10,20]]

                 Program 2: To print the nested list


                     Program2.py
                  File  Edit  Format  Run   Options  Window    Help

                  L1 = ['Orange', 2.0, 5, [10,20]]
                                                                                  Output
                  print(L1)                                                    ['Orange', 2.0, 5, [10, 20]]
