# Project:
# 1. Show to option to user 
#     1. Creat a file 
#         - call parent class metod to create a file using try except 
#     2. delete a file 
#         - call paret class method to delete file using try except 
#     3. Insert data 
#         - first get the file name by user in which he wants to insert data 
#         - then get data via user and insert it into provided file
