Create a Python program that prompts the user to enter one or more student records into a text file called 'studentGrades.txt'. Each student record will consist of a student id and gpa. When the program opens display all of the records in the file if there are any (create a function to do this), then use a loop to control the number of students added either by asking the user how many student records they want to enter or asking them if they want to enter more records after each one. After all of the records have been entered, call the function to print them out again so you can see the changes.
