Python: Write a program that generates 8 random scores (between 0 and 100), store them in an array, finds the best score, and then assigns grades based on the following scheme (use loops
wherever possible):
Grade is A if score >= best – 10
Grade is B if score >= best – 20
Grade is C if score >= best – 30
Grade is D if score >= best – 40
Grade is F otherwise.

The program written in python is as follows;

Note that the program makes use of function named checkbest

Lines written bold are comments and are used to replace the explanation section

#Program starts here

#This line imports the random module into the program

import random

#This line defines the function checkbest, with 2 parameters

def checkbest(score,best):

     #The following if condition implements the condition as stated in the

     #program requirement

     if score >= best- 10:

           grade = "A"

     elif score >= best - 20:

           grade = "B"

     elif score>= best - 30:

           grade = "C"

     elif score >= best - 40:

           grade = "D"

     else:

           grade = "F"

     #This line returns the letter grade depending on the above

     #conditions

     return "Grade: "+grade

#The main method starts here

#This line declares an empty list

array = []

#This line iterates from 1 to 8

for i in range(1,9):

     #This line generates a random integer between 0 and 100 (inclusive)

     score = random.randint(0,100)

     #This line inserts the generated score in the list

     array.append(score)

#This line sorts the list in ascending order

array.sort()

#This line gets the best score

best = array[7]

#This line iterates through the elements of the list

for i in range(0,8):

     #This line prints the current score

     print("Score: "+str(array[i]))

     #This line calls the function to print the corresponding letter grade

     print(checkbest(array[i], best))

     #This line prints an empty line

     print(" ")

#The program ends here

your answer would be the operating system.
