with open('StuGrades.txt') as f:

        We know that the lines in the document are: name, grade, name, grade, etc..

        So, if we have n lines, there are n/2 names and n/2 grades


    # The following lists are parallel, which mean that the grade at index i is for the name at index i

    names = list() # list to store names

    grades = list() # list to store grades as integers

    # Get number of lines

    n = len(lines)

    # Variable to store highest grade and the name of the person.

    # Set the values to the ones from the first person

    highest_grade_name = lines[0]

    highest_grade = int(lines[1])

    # Variables to store lowest grade and the name of the person

    # Set the values to the ones from the first person

    lowest_grade_name = lines[0]

    lowest_grade = int(lines[1])

    # Variable to store the average grade and the number of persons

    # Initialize with the value of the first person

    avg = float(lines[1])

    n_students = 1

    # Now read from lines 2 to n-2

    # We start at index 2 because we already used the grade from the first person

    for i in range(2, n-1, 2):

        name = lines[i].strip() # Use strip to remove \n

        grade = int(lines[i+1])

        avg += grade

        n_students += 1

        # Check if the current grade is highest

        if grade > highest_grade:

            highest_grade_name = name

            highest_grade = grade

        # Check if the current grade is lowest

        if grade < lowest_grade:

            lowest_grade = grade

            lowest_grade_name = name

    # Calculate average

    avg = avg / n_students

    # Display

    print(f"{highest_grade_name} got the highest grade with a score of {highest_grade}")

    print(f"{lowest_grade_name} for the lowest grade with a score of {lowest_grade}")
