Texts: Parallel Lists Write a Python program file called ParallelLists.py that uses parallel lists. The program should ask the user to enter the number of students, followed by the last name and grade for each student. Afterward, it should print a listing of the names and grades, as well as the average, highest grade (name and grade), and lowest grade (name and grade). When you have completed the program, please rename the file to "Your Name ParallelLists.py" and send it to me as an attachment in Canvas. Sample run: RESTART: C:$userDellKCclassworkHCCcSC105 - Program PreLabsPreLabO7AParallelLists.py Enter the number of students: 5 Enter the last name and grade for student 1: Davis 78 Enter the last name and grade for student 2: Jones 98 Enter the last name and grade for student 3: Larson 100 Enter the last name and grade for student 4: Morris 54 Enter the last name and grade for student 5: Smith 88 The students and grades entered are: Davis 78 Jones 98 Larson 100 Morris 54 Smith 88 Average: 83.6 Highest grade: Larson 100 Lowest grade: Morris 54
