Python Programming ONLY

I need help designing a program to record, search and create the students of a course in a file.

This program first shows a menu including the following options to the user, and responds according to the user selection.

Press 1 to make a new course score file.

Press 2 to search into an existing course score.

Press 3 to add more record to an existing course score file.

Press 4 to quit the program.

Apply try/except block to handle possible exceptions.

For simplicity, assume a student record contains student name and score. Each line of score file includes information of one student. Repetitive names in score file is ok.
