Problem $3$: CSV File Handling

Points Possible: $30$

This problem will provide you with an opportunity to demonstrate your understanding of reading from and writing to CSV files and demonstrating exception handling in your Python programs.$$

Instructions:

Write a Python program that writes user input to a CSV file, reads the data back from the CSV file, and incorporates exception handling. You will perform the following steps:

Prompt the user to enter a student$$s name, their grade, and the course name.$$

If the user does not enter a valid grade $($i$.$e$.,$a positive integer$),$your program should catch this error and ask for the input again.

Open a new file in write mode named student$\_$grades.csv and write the user's information to this file in CSV format.$$

Make sure you handle exceptions if you do not have write permissions for the file or other IO errors occur.

Now open the student$\_$grades.csv file in read mode.$$

Make sure your code handles any exceptions if the file is not found or other IO errors occur.

Read the content of the file and store it in a variable.

Print the contents of this variable to the console$/$shell$.$

Provide comments in your code to explain the logic used.
