Build me a simple python application

I am to write a program that would monitor the records of students in a text file. In order to access the functionalities of the program, I will provide the user choices in a menu using a command line interface (CLI). With CLI, users have to type their commands using the keyboard, therefore my program should provide prompts that tell the users what to do

use Python in coding the program the main user of which is a teacher, who will monitor the performance of students in a module. The program will manage the basic information of students and will record the marks of students in a class activity.
