                  Traversing Nested Lists

                  Nested list can be traversed by using the index operator.
                  Program 3: To create two nested lists.
                      Program3.py
                   File  Edit  Format   Run   Options  Window    Help
                   list=[2, [2002, "Orange", 65.5], [4002, "Orange Education", 46.5]]
                   print(list[2] [1])
                   print(list[1] [2])



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

                  Negative Indexing


                  Negative indexing means the index of -1 refers to the last elements of the list, the index of -2
                  refers to the second last element.
                  Program 4: Traversing a list by using negative indexing.
                      Program4.py
                   File  Edit  Format   Run   Options  Window    Help
                   list=[13, 25, 41, 63, 82]

                   print(list[-1])
                   print(list[-4])



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

                      Output
