                      ACCESSING A LIST

                      Accessing a list means traversing or visiting the elements of a list. There are various ways to
                      traverse a list, including positive indexing and negative indexing.

                       Program 16 A program to access elements of a list.

                          Program16.py
                       File  Edit  Format   Run    Options   Window    Help

                       # Program: Exam Schedule using Positive and Negative Indexing
                       exam_subjects = ["Math", "Science", "English", "History", "Computer"]
                       print("List of Exam Subjects:", exam_subjects)
                       # Positive Indexing → Accessing subjects from the beginning
                       print("Using Positive Indexing:")
                       print("The first exam subject is:", exam_subjects[0])   # First exam
                       print("The third exam subject is:", exam_subjects[2])   # Third exam

                       # Negative Indexing → Accessing subjects from the end
                       print("Using Negative Indexing:")
                       print("The last exam subject is:", exam_subjects[-1])   # Last exam
                       print("The second last exam subject is:", exam_subjects[-2]) # Second last exam
